So I've been trying to test the analog part of this card and its not 
going well.  That's not to say that the driver doesn't work, I'm sure 
its something I trying to do.  The DVB portion is working fine.  I'm 
trying to test using MythTV.

First off the driver is creating 2 video devices in /dev.  I'm guessing 
that one of them is the analog card with MPEG2 encoder support and the 
other is just a the frame grabber.  When I select /dev/video1 ( I used 
ivtv_first_minor to move off the PVR500 /dev links ) in the MythTV setup 
it recognizes the card ( probes correctly ) and shows me what my inputs 
are to select from.  I chose Television ( vs s-video etc ).  When I 
attempt to watch LiveTV it just never starts.  Actually it does start, 
and then exits back to the menu.  The frontend doesn't see a recording 
file being generated.

I can cat /dev/video1 to a file and get audio and video.  But the video 
is super dark.  I can barely make out any shapes.  But the audio is fine.
