DVD-RAM Compatability?



Does anyone know of any stand-alone DVD players that will play DVD-RAM disks? My computer DVD drive reads them, but I didn’t know if any regular DVD players could?


gdoggy, I have never seen a standard DVD player that will read DVD RAM, unless a Panasonic or a JVC model is/was made. Can I suggest getting in contact with them to see what there is, but I doubt it somehow. :slight_smile:


Is there incompatibilty among the different UDF formats regarding video playback ?

If you burn a DVD video on a DVD-RAM disk using Nero 6 it ends up as being in the format: UDF 1.02 the same as the pressed DVD
so there should be no problem to play these burned DVD-RAM’s on a standalone player like the new Panasonic DVD-S29

Does anybody know which UDF format is used when you burn a DVD-RAM disk in a Panasonic standalone burner ? :some people recently where talking about UDF 2.0 in this case.


I’ve got a Panasonic DMR-E55, and that burns to DVD-RAM as UDF 2.0. :iagree:




Thanks a lot merlin100 …

What I would also like to know is if a Panasonic standalone player reads DVD-RAM discs burned with Nero 6 in the UDF 1.02 format for examplee using a LG GSA burner (4120, 4160 or 4163)


Sorry, thats something I can’t help you with.




panasonic S35 dvd player does, i got one to go with the E55 for the other room, to save m ehaving to convert the RAM to a normal -R / quite a few of the models from the last 2 model years in panasonic read RAM discs now


A late post on the subject

But if you record the DVD-RAM, cann’t you dubb it to the recorder’s HDD and from there dubb it again to a DVD-R, if you need this disc format?


What do you mean by dub? Do you mean dubbing sound?


No, dub means simply to duplicate. As in copy or record.


Only some players from Panasonic, JVC and Toshiba can play DVD-RAM.
Note: DVD-RAM are not recorded in DVD-Video-Mode but in DVD-VR-Mode. So I don´t think that a DVD-RAM-compatible DVD-player can read a DVD-RAM recorded in DVD-Video-Mode.

Can´t try it by myself because I don´t have a DVD-RAM-writer


Hi, there!

A DVD-RAM is recorded in VR Mode only if you use a standalone Panasonic recorder (and some other standalones). On the other hand, apparently, if you use a PC, you can create DVD-RAM discs recorded in either VR Mode or Video Mode. At least, I can tell you that I was just reading that on Usenet today.

My question is, if I have a DVD Recordable [± or W] disc recorded in DVD Video Mode, how do I re-record it onto DVD-RAM in DVD Video Mode? Is there a software that allows me to do this? Apparently, Nero does, but I have heard of incompatabilities issues (unless, I suppose, a DVD-RAM in VR Mode is what is wanted). I am not an expert in any of these, but I have heard that the Video Mode standard uses VOB files while the VR standard uses VOR files. Again, I am just interested in a DVD-RAM in Video Mode and not in a DVD-RAM in VR mode.

If it is indeed possible to create a DVD-RAM in Video Mode, and I think it is, logic tells me that this disc should be compatible with any DVD reader, standalone or computer, that supports DVD-RAM, including the cheap Chinese ones. Conversely, DVD-RAM in VR Mode is not compatible with all DVD readers that support DVD-RAM.

If you know more of this topic, please advice.

I don´t know one cheap DVD-Player which can read DVD-RAM.

With TMPG DVD Author and Ulead Movie Factory you can import a DVD-RAM with VRO-Files to the HDD in MPG-format. Now you can re-author it and make a DVD-Video.


Hello, Gabe!

As for DVD-RAM compatability, if you are looking for a USD 30.00 or so player, it will hard to find. However, a USD 60.00 or so player with DVD-RAM compatability can be found.

I appreciate your information very much, but that is not what I am talking about. I am not talking about converting; I am talking about recording VOB files on the DVD-RAM disc itself. And this is possible to do according to some Usenet messsages. The question is how many standalone players can play this, let’s say, “special DVD-RAM disc” recorded with VOB files and not recorded with “native” VRO files.

I don’t want to post here the Usenet messages I am talking about, but if you E-mail me privately, I will direct you to them.

Best regards,

Can you tell me which DVD-Recorder can write vob-files directly on DVD-RAM? My two DVD-Recorders can only write to a DVD-RAM in VR-Mode -> vro-file

And which DVD-Player with DVD-RAM-reading can be bought for 60 USD? The Panasonic that can read DVD-RAM should be able to play VR-media, so I don´t know the meaning of writing vob-files on RAM.

When I save to .vro as mpg with Ulead MF or TDA I don´t convert it, that mpg-file don´t have less quality like the original.


Hi, Gabe!

>Can you tell me which DVD-Recorder can write vob-files directly on DVD-RAM? My >two DVD-Recorders can only write to a DVD-RAM in VR-Mode -> vro-file

No, I didn’t mean standalone recorders but PC (computer) drives that can burn data on DVD-RAM data discs.

>And which DVD-Player with DVD-RAM-reading can be bought for 60 USD?

You can find the list here (cheap and not-so-cheap):


>The Panasonic that can read DVD-RAM should be able to play VR-media, so I don´t >know the meaning of writing vob-files on RAM.

In order to write VOB files on DVD-RAM discs, you need a PC, a burn software, and DVD-RAM Data discs (not DVD-RAM Video discs) or DVD-RAM Video discs formatted as DVD-RAM Data discs. These data discs are fully compatible with DVD-RAM computer drives and, though not confirmed, on some (or maybe less than some) standalone DVD-RAM players.

Good to know.

The most drives are DVD-Recorders, but interesting info.

With PowerDVD 4 and WinDVD 5 I can play DVD-RAM with ifo and vro-Files without problems


You can play VR files out of you recorder or in a computer using a drive that supports DVD-RAM ( the number is increasing and in the fareast have allways been very popular).
The interest of VR (some home recorder do it using DVD-RW) are certain facilities that some HDD do not support, but the most important is that you can take the VR files, capture them to a Video Editor (where they will show as MPEG 2 files) and produce a DVD (where you get the Vob files) that most DVD players can read - we are considering that there are no copyrights and macrovision involved, as that would be a slightly different story.
So from you TV recordings you can produce your own DVDs with your comments and if you use a camera including your images or interviews to your kids, relatives, and so o.
If you consider it at a professional level, education, trainning, marketing and so on, you have a lot of possibilities --------- but DVD-RAM will be just one of the initial facilitators.
Obviously - you final work can be recorded to a common disc format: minus, plus, DL, RW, you choose…


Hi, friends!

Absolutely, I agree with everything you have said (Gage and Agomes), but I see that you are talking about authoring and/or editing. My approach is different as I would be interested in copying. So, let’s say that somebody lends me a DVD-R disc with VOB files full of video clips from MTV or VH-1, and I want to copy it. By using the computer, aside from the logical option of copying to another DVD-R disc (or ±RW discs) with the same VOB files, there is the option of copying these same VOB files on DVD-RAM discs as data. These VOB DVD-RAM discs are obviously fully compatible with computer drives, and conceivably with (how many?) standalone DVD players that can read data from DVD’s (like, I suppose, the standalone DVIX players if they also support DVD-RAM).

Now, I think I know the two top questions you might be wondering. First of all, why copying to DVD-RAM discs? Because of their better reliability and better protection when they come enclosed in cartridges. Second of all, why bothering with VOB files when you can use the native VOR files in the DVD-RAM discs? Simply because, if I want to re-record my video clips onto DVD-+RW discs, it is much easier to use VOB files to then be placed on DVD-+RW discs as opposed to using VOR files, change them to VOB files, to then be placed on DVD-+RW discs.

In short, I would like to use DVD-RAM discs as a sort of master and bridge medium. In point of actuality, this means to copy from DVD-+RW to DVD-RAM discs, keep the DVD-RAM discs as point of reference, and then, when needed, subsequently copy from DVD-RAM discs back to DVD-+RW discs, keeping the same VOB files all the way down. Of course, there is nothing wrong if you use DVD-+RW anywhere in the process; I just happen to think (personal opinion) that DVD-RAM discs are more reliable and better in general.

You’re right about safety offered by RAM
If you build a “master” using the DVD-RAM you just copy it to another support, I guess.
1/1 copy can put some problems because disc structure is not the same but you can copy wrote to an image and there you go from the image to the new support+

Please note that what differenciates a DVD video is the internal structure, not just the files. When you create one you get 2 folders: one for audio that seems to be empty and one for video (Video TS) where you have all the files, VON, info, menus, and so on. So to build a “master” you should build the structure as well, not just throw the files inside.
