I've been transferring Tivo programs from my PC to my Archos AV400 portable video player with no problem for a couple of years. The files get converted automatically (and greatly compressed in process) through the "synch" function to Windows Media (Video) files ,which play fine on the Archos. Then I made the mistake of upgrading my Windows Media Player from version 10 to version 11. Doesn't work at all-- instead of converting Tivo files to Windows Media (Video) files, WMP 11 converts them to "movie clips" which the Archos doesn't recognize. I could find no way to change this, no way to make it work, so I uninstalled WMP 11 and went back to WPM 10, where I'll stay.
