So, inspired by some of the posts I had seen on other forums, I went and visited the Best Buy stores (4 of them) in my area looking for dual layer media. Finding it in the last store (of course), I set out to try burning a dual layer disc and see if my NEC ND-2500A (purchased in a Pacific Digital box) would be up to the challenge.
My NEC drive has herrie’s 1.07V2 Beta 5 firmware installed on it.
I ripped a movie DVD as an ISO file using the version 18.104.22.168 of DVD Decrypter.
I then wrote the ISO to disc using a trial copy of vso CopyToDVD, version 22.214.171.124.
Disc write went well. No problems encountered. I had set the booktype to DVD-ROM and verified after the burn that it was set as such.
First test was DVDinfoPro. Using version 2.54, I ran the read error test using the NEC drive and it passed with no errors reported.
Second test was Nero CD/DVD Speed 3.01, again using the NEC drive. Results from that looked good:
Third test was back to DVDinfoPro to do an RPM test. I first used the NEC drive, then my Sony DRU-500A (which had just been updated with the firmware that allowed reading of DVD+R DL media):
Not really sure what to make of them. They don’t look that good, but I’m no expert at reading them.
Finally, I popped the disc in my set top DVD player and watched the movie. My DVD player, a Jaton PSD711K, has great DVD-R and DVD+R compatibility. None of the movies I have burned to DVD+R media have had the booktype changed and the DVD player doesn’t flinch.
With the DVD+R DL disc, it seemed to be the same. Movie played well … with one exception. I think its the layer break. At one part of the movie, the player gave a warning message (“Disc Minor Error - Clean Disc”) but then continued, although it looks like it skipped over about 10 seconds of the movie. I am not sure if this is where the layer break actually occurred on the media, or if the IFO files for the movie were now pointing to a layer break in a different position and it caused the problem. But there was that glitch.
Otherwise, the movie and all the special features played without incident. The player had no problem playing content on the second layer, and I observed no stuttering, artifacting, or other issues.
Unfortunately, I don’t have a Lite-On (or other Disc Quality-compatible) drive with which to check the quality of the disc write. I’ve been looking on eBay to get a cheap one, but so far, no luck.
I’m very pleased with my experience so far. Can’t wait for dual layer media prices to come down so more testing can be done. Although I do have three more pieces of dual layer media … what to burn … what to burn …
