I am trying to upgrade my mythtv box to the latest 2.6.22 kernel and latest
ivtv drivers and latest myth.  But I'm having a little trouble with the
ivtv_fb driver...

Here is what I've got running now.

--> ivtv drivers from the 2.6.22 kernel.  ( these load without errors and
look to be working ok )

--> ivtv-fb compiled from the 1.0.2 tar ball -- ( NOTE: I did have to
manually copy the correct ivtv-driver2.h to ivtv-driver.h because it
wouldn't load when it used the ivtv-driver1.h -- I think this has something
to do with the way detection of the 2.6.22 kernel is done.   I'm running
GENTOO BTW.)  But the frame buffer loads now without errors

--> IVTV X driver compiled from source downloaded from subversion

X and mythfront end run great over the frame buffer, but playback using the
PVR-350 decoder doesn't work..

Trying to troubleshoot the problem -- I went back to the command prompt and
played the video using

cat file.mpg > /dev/video16

This works great before I load the ivtv-fb driver, BUT once I load the
ivtv-fb driver ( with modules.conf: options ivtv_fb osd_compat=1 )

The playback gives me a just a black screen -- although I can hear the
audio...

So I think the problem is the ivtv-fb driver... --

Am I testing this properly?? Or am I missing some command that needs to be
run to tell the fb to switch from showing the X content to allow the video
to be played??

This all worked under earlier kernel and older ivtv versions ( actually I
think I was using ivtvdev driver not the X ivtv driver... )

I saw some people saying Xv with ivtv would allow playback over the ivtv
frame buffer without using the PVR-350 decoder, but I don't know how to get
Xv working with the ivtv-fb.  If anyone can explain that I'll give that a
try, but when I tried running myth playback without the 350 decoder to the
ivtv X driver the video is very very choppy..   Maybe Xv would help that,
but the way I had it working before with the HW decoding was so nice I'd
really rather get that working.


DMESG OUTPUT looks clean to me..
