[mythtv-users] PVR-150 Video Quality

I recently set up mythtv 0.19 (running on an FC5 machine) with a
PVR-150MCE. The install went perfectly and everything seems to be
working well. The only problem I have is with the quality of the
PVR-150 video both in live TV and in recordings. The color is almost
non-existent (very grey picture) and the picture itself is very
grainy. I have made adjustments to the hue, saturation, contrast and
brightness as well as doing some fine tuning but have had no luck in
improving the video quality. I also tried upgrading the ivtv module
to 0.7-111 (from 0.6.4 I believe) but that didn't change anything.
Can someone else who has a PVR-150 help me out?
Thanks!
