In getting the HVR4000 Analog TV I have found a few things. I can not go 
above 320x240 unless I set in 2 places the default size 720x576

cx88-core.c ~line 1011 it goes
cx88_set_scale(core, 320, 240, V4L2_FIELD_INTERLACED);

cx88-video.c ~line 988 it goes
 fh->width    = 320;
 fh->height   = 240;
 fh->fmt      = format_by_fourcc(V4L2_PIX_FMT_BGR24);

Why set this so low by default? in the HVR4000 I have to change this to 
720x576 to allow higher and change the chroma to UYVY to allow anything 
above 640x480 to look correct.

I use to test this all the below, but under mythtv I have the same problem 
with resolution unless I change things.

/usr/local/bin/vlc --v4l-chroma=UYVY --color -vv 
v4l:/dev/video0:size=720x576:norm=pal:channel=0:samplerate=48000:frequency=511250:adev=/dev/dsp1:audio=1 
 --sout '#transcode{vb=2048,ab=128,vcodec=mp1v,aco
dec=mp3,channels=2}:std{access=mmsh,mux=asfh,dst=:80"'

Any comments?

Thanks
Craig
