You need to provide additional details, you didn't give enough info for the members who know about this stuff to help you. Where did your VOB files come from? Are they live action? Cartoons? Original footage from a video camera? Files traded over the net? Converted from DiVX? They might have been transcoded from another format optimized for computer viewing, in which case they're never going to look great on a 32" TV set. As far as I know, you can't really "fit the DVD quality to the display size" once you already have a VOB, but I could be wrong: more expert members can jump in if you tell us a bit more about these VOB files.
