[mythtvnz] Green screen .. help please

Thu Jan 22 06:09:57 GMT 2009

Hi Simon,

That command results in:

Found Xv 2.2
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (XVideo)
  Minor opcode of failed request:  14 ()
  Serial number of failed request:  11
  Current serial number in output stream:  11

Looks like I am having issues with XV.

By the way, this box has the Intel G45 chipset, don't know how to get the
latest drivers for that as they are included in the kernel. I am reluctant
to try a new kernel that hasn't been released by ubuntu.

Cheers,
bernie
