Hi,

I have a bunch of video podcasts that I subscribe to and watch on my PC. The videos are described as iPod/PSP compatible, and of course don't play on my n800. I bought Quicktime Pro to transcode them, but can't seem to get a format that will play . I've tried avi, xvid-avi, and mp-4, but media player reports "unsupported format" in each case. I'm probably missing something obvious - does anyone have any ideas?

Thanks!
Dan

Go here and use this media conversion program made specifically for the 770/N800.

https://garage.maemo.org/projects/mediaconverter/

see http://maemo.org/maemowiki/VideoEncoding

the n800 has a bug with long videos https://maemo.org/bugzilla/show_bug.cgi?id=991

Thanks euchreprof. I tried using mediaconverter, but just got the errors below. I already have the latest mplayer installed on my computer, so that can't be the issue, and the files i'm trying to convert are mid-sized ipod compatible downloads from google video. Any suggestions on how to get media converter to play nice?
