Had this problem a couple of times

Rip DVD with Smartripper, when converting with DVD2SVCD check the files before burning, and it's like everyone is talking in really deep voices

The Encoded audio file is like this, but the Extracted .ac3 file is OK, got round it a couple of time by converting the .ac3 file to a .wav file using Goldwave and then re-encoding using TMPGEnc, but I like the simplicity of DVD2SVCD !!

Anyone know whats causing this ?
