DVD's stop half way through

I have been using shrink w/decryptor to make my backups. I don’t know if its because anydvd is running in the background or where the problem is but my backups stop playing half way through. Any suggestions?

what exactly happens when they “stop playing half way through”? do they play all the way through on other systems or on standalones? and what type of media are you using? without more information, i’ll just assume that it’s an issue with bad quality media.

I use TDK (CMC & TY) They just stop playing and stop the dvd player also. I tried reducing speed fm 8x to 6x and it still happens. I was using 2C8 firmware.
