I have X working on the PVR-350 output with the latest ivtvdev driver
(v0.8) but I'm really confused with mythtv : I can't watch MPEG-2
recordings or live tv except sometimes at really poor framrate but xvid
transcoded files are working, besides that the GUI of the frontend is
displayed without any problems. I tried two things : first compiling
mythtv with Xv second without Xv and no changes cause I read that the
PVR-350 doesn't support Xv. Is this patch intended for this problem or
am I doing something wrong in an earlier stage of my setup.
My setup :
mythtv checked out from cvs today
gentoo-2.6.9-r4
ivtv-0.3.2a
bttv-0.9.15
PVR-350 model 992 (PAL-SECAM)
xorg-6.8.0-r3

The attached patch is a slightly cleaned up version of a patch
several people have been using with recent ivtv drivers.
I have modified the original patch to
1) Work with older ivtv code
2) Have an option in settigs.pro to allow the inclusion of an
installed ivtv header file.
I originally had code to check for the existence of the installed
header file but there were some objections to this so I have made it
an option in settings.pro which by default is off. I would prefer it
to be on but I think we probably need to have had a couple of releases
of ivtv that install the header file before we make that the default.
This patch improves the performance of the OSD update code in 2 ways
1) ClearOSD is performed by a bitblt operation on the card which
is a single api command rather than a complete dma of the screen
2) It calculates the region of the frame buffer that needs to be
updated and passes it out so that only that region is sent to the card
rather than the whole screen for every update.
Any problems or suggested changes let me know.
