Sigh...no video, logs included, xawtv does work now. Huh?

I now know that somehow the NVidia proprietary drivers were killing off video access - xawtv wouldn't run. I'm now on the VESA driver, xawtv works, I can live with 800x600, time to move on.

I'm on Ubuntu Intrepid. I've done these directions to the letter:

I have no errors in the Apache log and obviously with xawtv working, the BT878 drivers are in good shape.

I've turned ZM's diagnostics logging to "9" and wished I could turn 'em up to "11" (gratuitous Spinal Tap reference).

I have some strange stuff going on at /var/log/messages:

Not sure what that's about.

There's also odd stuff in the zm_debug logs at /tmp:
