"would ipod updater 2004-08-06 work with ipod linux and the other software?"

Check the forum/place that wrote said application.

"and is there sound on the videos?"

The iPod (so far) has music playback and shows pictures (iPod Photo) but movies or "videos" are not supported (www.apple.com)

"and could u put liek movies on? thank u for ur time"

Sorry, what is a "liek movie"?
