I've been using Mactheripper and Handbrake for my DVD's. I've been using VisualHub to convert .avi files for those DVDs that I had already backed up from when I was using my Xbox 360 as a media center prior to ATV purchase and it works well. My question is what is the best way to convert TV shows for the ATV? Right now they are in .avi or .mkv. If I convert in VisualHub and use the "Join files" option will that create the mp4 with chapters? I really would like to not have 10-15 episodes for each season separate. Thanks for any suggestions.
