If you ever think it's not seeing it, look in the log and look at the statusbar for clues as to why. Most likely, it'll say 'Device Not Ready (insert some reason here)'.

What other differences could there be?! Well you know, ones you could actually see I mean! Hardware is different, firmware is different but I'm not sure if there have been any speed improvements (that's the bit you would 'see'). I guess DVD+R DL might be faster, or DVD-R DL. Other than that, the 1640 was probably maxed out anyway! Burn quality in general is supposed to be better than the 1640 and previous models. Any glitches the 1640 had, have probably been ironed out.

Because they're not supported.

Nice drive, good + fast at scanning too. Might aswell get a 1655 though. They're hard to get in the UK (well, the 'Retail' model is) but newegg have them in the US. btw, you want the retail one

Yeah try and send them back and get verbatims instead. Also, your burner (OEM LiteOn 852) is actually quite an old one now (by todays standards), it's quite possible that hardware/firmware isn't great for DL burning.

Nope, none at all! I guess the person who provided the info the first time around didn't take those images into account.

It probably doesn't check for a valid filesystem. ImgBurn does. Send me the first 5mb of it and I'll tell you the real problem (plus fix my program if it needs it) The tool I posted HERE will help. Thanks

Only 1 piece of advice here... avoid RITEK DL discs like the plague! Get some Verbatims and I'm sure you'll have much more luck. Yes, they do cost more, but there is a good reason for that - they work!

Mount that ISO in Daemon Tools. Load up PgcEdit and point it at the Daemon Tools virtual drive. Then have PgcEdit recreate the ISO file - it will make a proper image (if possible) with a layer break position that can actually be used.

Eh, What's up doc?

Might be an idea to hide the DL discs away from yourself! As for warning messages, I'll see what I can do

All drives tend to follow the MMC specs now so drive support isn't really an issue. It's more a case of testing to find problems in their implementation of certain commands! It's also things like bitsetting and drive specific features / tweaks that need to be configured. i.e. all the cool stuff BenQ offers. Obviously newer drives also support new burning features - like layer jump recording etc. These features need testing as from what I've found, no two drives behave in the same way!
