Any help with this would really be appreciated. The gear: Ubuntu (Lucid Lynx) on older Toshiba laptop - CAT5 to Linksys WRT54G Running Twonky Logitech Revue - WiFi from WRT54G (Disclaimer: I'm not much of a Linux guy. I tinker. When the laptop in question went blort with Windows, Ubuntu rescued it. I don't have a Windows box available to me at this point.) The Problem: From the Revue I can see most of the vids stored on the laptop. A few won't play...that's probably a format issue I can fix. However, the ones I can get started only stream the soundtrack...no video picture. That's the puzzle. Sound yes; picture no. Thoughts?
