Problems when trying to burn a data dvd (ISO)

[Raymomofo]

Hello...I'm new to these forums and am seeking help for backing up my files on dvd+r discs with my hp dvd writer 300n

I've been having problems burning data dvds.. i'm trying to back up my .avi files but keep on experiencing problems

everytime I burn it using Nero 6. it says that the burn is successful, but it fails the verification check. The DVD is readable, but about half of the files do not work. Half of it works perfectly while the rest is unreadable

I use memorex dvd+r discs and i heard that they were low quality...but i just wanted to see if my burner worked properly. It burn's cd's properly (both data and music). I doubt it's the program since i have used nero and recordnow (both have same issue)

I dont know what is causing it.. I tried using Nero Info tool and when i looked at the ASPI tab for system ASPI, it said ASPI files are missing...Does this have anything to do with it? The only ones listed there are
WNASPI32.DLL and WINASPI.DLL...

I appreciate any assistance in solving this problem...

I did some research and found out that the media code for memorex discs can be either ricoh or CMC's...

I discovered thatthe discs I'm using are of the CMC quality. Could this be my problem?

What firmware are you using?
What is the EXACT mid code of the discs? CMC MAG F01 ?
It could be that your current firmware has an inadequate write strategy for these discs.
Upgrade your firmware if possible!
