LiteON 411s and Commodore DVD-R 4x media = no go, help

hi there… I’ve bought some DVD-R media from Commodore (www.commodore-media.com) since the shop didn’t have any more Dysan DVD-R’s and the shop assistant assured me that the media would work flawlessly on my LiteOn 411s DVD burner.

But I guess he lied :wink: I can only burn them @1x in Nero, plus they are nearly unreadable afterwards in the burner, let alone in a DVD player or a DVD-ROM drive.

Unfourtunatelly, the shop doesent want to exchange them, denying that the shop assistant assured me that the media would work - so now I am stuck with 50 pcs of worthless media that I can’t do anything with…

Would it be possible to modify then firmware of the 411s to accept these media and burn them @ full 4x speed? Am I wrong thinking that the problem is caused by the fact that the media should be written @ 4x and not @ 1x? Or does the DVD writer indeed need to know how to be calibrated to write to these media properly?

Any suggestions would be welcome… oh yes, one last question, what proggie do you use to identify DVD media?

Thanks a lot for any help…

Bye

If they won’t burn well at 1x, they certainly won’t improve at 4x, even if you could do so, which you can’t.
Use SmartBurn from the LiteOn site to identify your media.

Ok, thanx for the proggie although when I read the MEDIA thread ppl gave more info about the DVD’s, maybe there is a more comprehensive proggie out there… And if this helps, SmartBurn spits out the following about the Commodore DVD-R 4x media:

Drive Type = DVD DUAL
Disc Type = DVD-R (Single Layer)
Disc MID = 56 44 53 50 4D 53 (VDSPMS)
Disc TID = 00 04 41 42 20 30 (…AB 0)
Nominal Capacity = 4.38GB
Manufacturer Maybe = Unknown
SMART-BURN Speed Limit = 1.0X (Write)

Try DVDInfo-pro and see what it says about the stuff. But it’s not looking good. :eek:

well… I downloaded the proggie and tried the “Show Complete Media Code” option and got this:

00000000 00 6C 00 00 01 40 C1 FD 9E D8 52 00 02 EA 0B 14 .l…@…R…

Well, maybe this may help but I doubt it… Is there any way to contact LiteON and ask them to include this media in the next revision of their firmware?

Thanx 4 help

best advice i can give you… sell the rest of your dvds on ebay. i buy mine from here:
http://www.stores.ebay.com/id=109059311&ssPageName=L2
find the cheapest ones and and be sure to request dvds with media code:
00 6C 00 00 01 40 C1 FD 9E D8 52 00 02 EA 0B 14 .l…@…R…
76 78 80 00 03 56 44 53 50 AD 53 00 04 41 42 20 vx…VDSP.S…AB
30 31 00 00 05 E8 80 00 00 00 01 00 06 0B 10 11 01…

you should email them and let them know what you want before you buy anything. good luck

Thanx Mea20, unfourtunatelly I live in Europe (Slovakia to be exact…) so I don’t think I will be able to actually sell them …

I was thinking maybe it would be possible to hack the media code in the 411s firmware, maybe replace one genuine one with the media code of the Commodore DVD-R’s - could this help if the media would have a similar info as Commodore DVD-R?

You can put all the media codes into the firmware that you want, but it won’t improve the burn quality unless you include the correct laser calibrations. But I doubt that this media will burn well in any case. It does burn at 4x in the Pioneer 106 burners, but not very well. Nobody really knows where it comes from. Future firmware updates might improve things, but basically you have some worthless media.

VDSPMSAB01 and VDSPSAB01 is about the worst media I’ve had, both these codes is fropm the same manufacturer but only the VDSPSAB code is supported by the Lite-On. The VDSPMSAB code will to my information be supported in the next firmware version.

But even when supported do not expect very good results from these really crappy discs. They have problems in all writers I’ve tested them in - including the pioneer DVR-106 which I consider to be the king of DVD-R compatibility and write quality.

Ok, thanx a lot for the word of advice… I guess that the next time I will insist on my trusted brand of DVD-R media (from the cheapo sector Dysan seems like a winner for the 411s).

Again, thank you very much for your suggestions.

weeeelll I guess I’ve solved my problem now :wink:

I used my original firmware extracted from the drive, compared that to the new 811s FW that is discussed in another thread, added the media code for my Commodore DVD-R’s by replacing a similar media code (VDSPMS…AB1) with the one of the Commodore DVD-R’s and VOILA! - I can now burn @ 2x and @4 x speeds and best of all, the DVD’s are readable! :wink:

Average PI errors for a full DVD are around 10 and PO is only around 0.040 ! What a huge difference and well, what can I say - these DVD-R’s give me better results than Princo and Dysan, so they are not THAT bad after all :slight_smile: But I sure won’t buy another pack of these media, just to be on the safe side of things

Hallo,
I have the same problem with this disc…
Can you send me this firmware?
THANKS!:bigsmile:
