Ok, I dunno where else to look.  I've searched my brains out and tried just about everything.    Using:
 
Knoppmyth R5A22
SP130000 motherboard
PVR-350
 
ivtv kernel 0.4.0
ivtvdev - not sure what version, but not current. Found at:
 
- PVR 350 is enabled in Mythtv
 
SYMPTOMS:
- Watching TV gives crystal clear playback.
- Watching untranscoded TV recordings is clear.
- Watching DVDs gives extremely poor framerate
- Watching transcoded recordings gives poor framerate
- Watching downloaded mpg videos gives poor framerate
 
This is all happening through the PVR-350 tv out.
 
I've tried everything under the sun I can find from a million different sources, and right now I'm simply amazed I haven't completely cratered my mythtv installation.  
 
I tried going to the latest ivtvdev drivers, but when I do it fails with the following:
 
(II) v4l driver for Video4Linux
(II) IVTVDEV_TST: driver for framebuffer: PVR-350
(II) Primary Device is: PCI 01:00:0
(WW) ivtvdev: No matching Device section for instance (BusID PCI:0:20:0) found
(EE) No devices detected.
Note that my card is at 0x14 (which translates to 20 I believe)
 
Switching back to the older driver works fine except for the frame rate problems listed above.
 
Any thoughts?
 
Paul
