"Saturn ring effect" with DL media, bad media?

[impmon2]

I have had 100% fail rate on Verbantim DL medias for some reason. When it burns, it does fine for the first 2GB then the burner acts up and spits out the disc with write fail error message. The disc from beyond 2GB mark looks like old style records with several obvious skipped tracks. Or a close up image of Saturn's rings

I have tried with other brands (single and DL +/-R, they burn fine but not Verbantim, it always end up looking like records. Phot of the CD up close (a bit dark as I had to do without flash): http://personalpages.tds.net/~wilykat/DSC00747.JPG

I use Liteon DVD burner 1693S and I have tried various burn speed.

Incompatiable media? Or just bad luck?

From the looks of your DVD picture, that is messed up. I didn't see what program you were using to burn with. I use DVD Decrypter to burn. ISO Read>ISO Write. I have 100% success with Verbatim DL. You can also use the newer ImgBurn program.

It may be the burning program, try one of the programs mentioned above. If not, it may be a problem with the burner. Verbatim is usually the most compatible DL media.

It is not casued by the media, itself. What software did you used ?

[impmon2]

I used TMPGEnc DVD Author initially and tried again using Nero to burn the ISO created from TMPG DVD Author. So 2 different programs, same problem. But like I said only with Verbantim media. Maybe the burner needs a firmware upgrade or something?

Use DVD Decryptor or ImgBurn to write the ISO. If you have AUDIO_TS and VIDEO_TS folders, user RecordNow 7.3. You'll find those 3 apps seem to work best according to posts here.

Does the disc burn successfully? Is the data burnt retrievable?

Look at thoese rings, I think answer is no.

I've got quite a few RWs that look like that and they still read back fine.

I tried using ISO Buster on the failed disc, it was only able to partially salvage a coupe GB so it's defiantly not readable in the latter part.

I'll try both ImgBurn and RecordNow and see if it works. Only got one blank DL left >_< those don't come cheap.

Quick update: wrong burn speed setting seems to be the cause. I noticed that when I tried imgburn and when I retested with TMPGEnc DVD author and Nero, both offered 4x burn setting but the DVD I have are labeled for 2.4x only. I manually changed to 2.4x and no more problem. It seems Verbantim DL discs are not compatible with 4x burn speed.
