[mythtv-users] (somewhat off-topic) compiling the TBS 6981 driver

[Mick Sulley]

I recently started work on resurrecting a Myth box that I played with a 
few years back.  Started with a fresh install on Debian and could not 
get the TBS 6981 to work and after several mails back and forth with TBS 
support I started again with Mythbuntu.  I still had a few problems (and 
more mails to TBS).  The final issue was that there were "disagrees 
about version of symbol" and "Unknown symbol" errors in the dmesg log.  
There is a fix gor this in the FAQ section in the TBS Linux driver package
Mine are now visible, although I don't know if they actually work yet, 
more to do on the system.

Hope that helps
