So I ripped a bunch of TV episodes from a DVD (which I legally own) to put on my iPad. I used the iPad preset in Handbrake. All the files ripped fine and played fine. I copied the files into iTunes, spent a good hour or two adding and correcting metadata on them, went to play them back, and half of the files are now completely missing audio. Transferred to my iPad anyways. No audio there. Opened the file in VLC, no audio there either. The audio track in VLC was set to Disabled. Tried switching it to English, no dice. It still stays on disabled. The original source files (before I copied into iTunes) play fine. Seems like iTunes completely wrecked the files, and now it's looking like I may have to reimport them and retag them, possibly only for iTunes to jack them up again. Anyone know what the deal is?
