Using Convertx 4. Im in the process of converting and burning hundreds of tv episodes from avi files downloaded from one source. Running smoothly until I run across some files that when converted, the audio is, I dunno, whats worse than "stutter"? Its useless. I have tried them again several times and just keep making more coasters. I re-downloaded them but no love. I have gone to different sources looking for different versions but since they too dont work and are the same size I assume they are the same files with different names. They play just fine but refuse to convert properly. any help would be appreciated.
