hi, i've downloaded a videopodcast from itunes, but when i want to watch it it says (in german) "wrong/unsupported video format". i have an ipod touch 1g with 2.2 firmware (jb). i didn't pirate the video, it comes straight from itunes. p.s.: this video is an hd-video.....normal videopodcasts work on my touch. does the ipod not support hd?
