I have all my DVD ripped to ISO. Now, after all the reading, I realize that I will have to convert/transcode to something else before I can stream it to Ipad. Now, may I ask all of you for a bit more info, before I decide on what route I am going to take. 1. As I have always managed my video by keeping a completely native ISO file, I don't know much about various file formats and resolutions, e.g. avi, mpeg, h264..... What would be the highest resolution and best format to keep? Since I will have to convert/transcode my ISO to another format, I might as well keep the highest fidelity possible. 2. Once I decide on what file format I am going to convert/transcode to, could anyone here suggest a simple program to do BATCH conversion for my hundreds of DVD ISO files?
