I have two home computers on a network, one is a 2GHZ Celeron w/384MB mem, the other a 2GHZ Pentium w/640MB mem, WIN XP on both. Trying to backup a Xena WP DVD. On the Celeron, the backups work perfectly 99% of the time. On the Pentium they fail all the time. On the Pentium, the copies always have problems with the DVD menu system (you go into a menu branch and there is no response to menu selections, the menu choices will not highlight). After some trial and error to eliminate hardware/software issues I've narrowed the problem down to this: On the Celeron I encoded the DVD to an ISO file without compression, mounted with Alcohol and verified a good copy was obtained. I copied the ISO to the Pentium and tried to compress down to 4.7G and saved as ISO. Mounted with Alcohol to view and I get the same locking DVD menu problem. The weird thing is that the error is always the same whether I encode directly from the DVD or from the ISO file on the hard drive and always on the same DVD menu branch (from the same DVD). I've tried 5 different DVDs and always the same (the menu branches lock up). Perfect copy on Celeron and bad on Pentium. Other thing I've noticed when I've tried compressing and burning from an ISO Alcohol mounted uncompressed DVD copy (a good copy) directly to the DVD, the DVD is always unreadable and by looking at the DVD it seems like only the first track was written on the DVD even though the system looks like it's actually burning. Also, the temp DVD files that are created on the hard drive can't be viewed. WinDVD reports that these DVD files are invalid for viewing but this is what DVD Shrink created to use to burn to the DVD.
I'm starting to think I have a defective Pentium chip, or bad memory...Can anybody shed some light on what might be going on?
Add'l info...
Both systems have 99% of the same software installed. 1% difference would be in the drivers, different Motherboards, video cards, IDE controller cards, hard drives and DVD burner.
I've tried 5 different DVDs and always the same. Perfect copy on Celeron and bad on Pentium.
I'd like to use the Pentium because it has the faster DVD burner and seems to be a bit faster in processing...
While I wait for a clue from you guys I'm gonna trying playing with the memory sticks to see I have a bad one (I have 3 installed.) And if that fails, guess I'll swap DVD burners on these machines.
Thanks for your help guys..
