Edit:

Sorry, overlooked the “-R” (works different for +R and -R).

could one of our kind moderators or admins forward this media code to liteon for support in the next firmware update?

:slight_smile:

thanks.

the problem is, there are no future firmware updates planned for 411/451/811/851 according to some of cdfreaks liteon contacts.

rds04,

I think they will need full “media code”.

Like this:

Good news Yup.
Bad news: they are utterly crap.

http://www.dvdrhelp.com/dvdmedia.php?selectmedia=277

I bought 5 of them way back when i still owned a Pioneer burner. Even with Pioneer, it could not burn this well. Errors toward the end of discs were off the chart and i gave up on them. I returned remain packs promptly the next week.

If it is the same media i think, no way on earth it can be used at 4x. Sorry…

This is 2x media - so they should only work at 2x.

If they’re sold as 4x - whine at the dealer.

thanks for the responses.

these are clearly printed as 4x media on the face of the disk. if i only had a digicam i could post a picture. these are made by melody of taiwan but these are not yet on their website. their 2x media has a different color and are clearly labeled as such. could be a new product. and this one has azo dye clearly labeled unlike their old products.

saw the link and it seems to me that the media code is not entirely identical.

:slight_smile:

Finding the REAL certified speed of the disc is easy:

Download DVD.Identifier ( http://DVD.Identifier.cdfreaks.com )

Run it on the discs and post here, should look something like this:

Unique Disc Identifier : [DVD-R:PRINCO]

Disc Type : [DVD-R]
Manufacturer ID : [PRINCO]
Disc Application Code : [Unrestricted Use : Consumer Purpose]
Recording Speeds : [1x - (2x)]
Blank Disc Capacity : [2,298,496 Sectors = 4,489.3 MB = 4.38 GB]

[DVD Identifier - http://DVD.Identifier.CDfreaks.com]

The speed on the “Recording Speeds” line is the real certified speed of the disc. If it says 1x-(2x) then it’s only 2x and you should whine at the manufacturer/dealer of your media. If it says 1x-2x-4x then you should whine at Lite-On for not supporting the media at 4x.

Edit: oops I see you posted this already :o

And there it says 1x-(2x) = this is 2x media = whine at media manufacturer/dealer. This is not Lite-On’s fault!

If you care to know I’ve also mis-labeled MMORE discs here. They are 2x but marked as 4x - even on the disc. So yes such mistakes do happen.

Sorry for keep letting you down, but i think that media along with the older 1x caused CMC a bad name in the beginning. After that CMC.AF1, CMC.MAG.F1 have been great for me.

If you can return them, you might want to do that. I think you are better off with newer cheapos. If you can’t, kprobe the discs making sure that toward the end, it is still readable.

just made an e-mail to melody group about your observations. i actually made a link to this post.

thank you all for your help.
