I haven't gotten my iPad 2 yet. I don't own a 1st gen iPad. While I was waiting for my iPad 2, I thought I would convert some of my videos for viewing on the iPad 2. But what bitrate to use? I read someplace that the 1st gen iPad would handle 2 mbs, but choked on anything over 5 mbs. It seems that many of my videos are encoded at around 4 mbs... I am hoping that will play okay. The videos are mostly 720x480, so that shouldn't need to change, but they are all in mpeg-2, so I will be converting to mp4 with an h.264 codec. Can I just leave the bitrate as it is? Or should I down shift it?
