I bought Pavtube DVD to iPad Converter software in order to convert episodes of a DVD to iPad format for a journey next week. The quality of the video is superior to the iPhone format of the series which I converted with Handbrake.
iSkySoft has been giving away free copies of some of their software. I picked up the dvd to iPhone converter and it worked very well. They are giving away a DVD-library software now (only works for mac) but they also gave away 'iMedia converter' which I also picked up and seems to work well also.
