[pvrusb2] Poor analog picture on HVR-1950 after upgrade to 2.6.28 kernel

[fivenote]

Mike,

my ctl_video_standard/enum_val gives...

none
PAL-M
PAL-N
PAL-Nc
NTSC-M
NTSC-Mj
NTSC-Mk

I did the following...

(1) shutdown mythbackend
(2) cat NTSC-M > ctl_video_standard/cur_val
(3) ran mplayer /dev/video0
(4) verified that ctl_video_standard/cur_val = NTSC-M

Same problems with the picture.
