[mythtv-users] Re: [mythtv] non-Xv display support in CVS.

(I actually had to type this in rather than cut &
paste so excuse the cuts.)

----------------------------------------
Changing from None to WatchingLiveTV
Over/underscanning. V: 0.000000, H: 0.000000, XOff: 0,
YOff: 0
X Error: BadValue (integer parameter out of range for
operation) 2
  Major opcode: 1
  Minor opcode: 0
  Resource id: 0x0

[next part repeats 7 times]
XError: BadWindow (invalid window parameter) 3
  Major opcode: 18
  Minor opcode: 0
  Resource id: 0xa00001

Couldn't find Xv support, falling back to non-Xv mode.

# [ Slower performance warning ]

Segmentation fault
----------------------------------------

I tried the NO_SHM with pretty much the same results.
The getshm error seems to have disappeared...

For color depth and resolution I tried
  800x600x16 (vga=788) and 640x480 (vga=785)

The mythtv capture settings should all be at defaults.
