Ok so recently I acquired a pack of 9 volumes of a DVD set, and I want to put the DVDs onto my iPod touch. So far with the first 4 DVDs I have been successful in doing this, using handbrake on my Mac. I set the DVD as my source and my preset default on the side screen is iPhone and iPod touch. The DVDs were high quality and I had no*Problems with converting and viewing them, but now when I try to convert the 5th DVD, it encodes but the encoding stops at 100% and then nothing happens. When I look at the activity window on handbrake, the main thing it seems to say is 'error reading NAV Packet. I tried playing the DVD on VLC but it won't play on that either. It just says 'error reading NAV packet' again. I tried playing the DVD on VLC on my PC and it works fine there, but when I try to convert it using handbrake on my PC the video turns out fuzzy with colored blocks and lines all over the screen. It's weird because I tried DVDs 6, 7, 8 and 9 too but I encountered the same problems with 6, 7 and 9 but not 8. Any help please?
