Sound on stand alone player, no sound on Computers

[snotyad1]

A few months ago I backed up a movie on a Ritek G03 DVD-R using a Pioneer A05 (DVD Decrypter, DVD2one (movie only), and Nero 551028). It plays great on every stand alone DVD player I have ever tried it on. It still plays great on stand alone players, but it has no sound when I try and play it on any computer. Sounds for everything else on the computers, but not this disk. I can copy it and have the same result – sound on stand alone, not on computer's. What could cause this to happen?

You are probably missing the AC3 codec on your PC. There is a free one in the tools section.

Thanks, I'll try it when I get home. However, I believe it used to play on the PC's.
