Ok, so I decided to burn some AVI files to DVD using Nero Vision 4 and Nero Burning ROM. I put everything to high quality, and the burn is successful. However, since I have subtitles on the movie, they seem to be cut off at the bottom. It seems like its too vertically stretched to fit perfectly on a regular non HDTV. It's so annoying when subtitles are cut off the screen. Any ideas on how to solve this?
