[mythtv-users] WinTV-PVR-USB2 Jumpy Video

[Mark Goldberg]

I've installed a WinTV-PVR-USB2 on a FC 6 ATRPMs Myth System,
everything updated. The cd from the box could not be read, so firmware
is from pvrusb2_inf_24117.zip downloaded from the Hauppauge web site.
The problem is that the video is jumpy,
maybe a couple of times a second, repetitively. If you look on an
input (S Video) with a news crawl along the bottom, you can see it
jump. The audio also seems to not be synced with the video sometimes.
I've tried a few settings in the /sys/class/pvrusb2 tree, but could
find nothing that affects it so far. I'm using an S video input from a
directv reciever, at 720x480. Any help or suggestions would be
appreciated. DMESG is as follows:
