[mythtv-users] PVR350 TV-OUT (PAL) not Working (probably X-Server
Config?)

Hi all,
my problem is now partially solved. The cat mpg to dev/video16 works properly
and I can see a clear picture now, but still when I start the X-Server now
the quality "improved" from a picture where one could just guess what is
displayed to a "double" picture (meaning that I have two mouse pointers, two
menus appearing and so on.) So could any of your guys give me some additional
information what to do now?
What I have done to solve the problems before is:
Use the suggested script to test....
insmod ivtv tuner=5 ivtv_pal=1 ivtv_debug=1
insmod tuner pal=1 type=5
insmod saa7115
DEV=/dev/video1
/usr/bin/test_ioctl --device=$DEV -u 0xff
/usr/bin/test_ioctl --device=$DEV -p 4
/usr/bin/test_ioctl --device=$DEV -f width=720,height=576
/usr/bin/test_ioctl --device=$DEV -v input=7,output=1
insmod msp3400 once=1 simple=1 standard=0x0a
# Load the saa7127 without any tv output
insmod saa7127 enable_output=0 output_select=2 pal=1
# Send something to the decoder which seems to fix the tv display
# This is a short mpg captured using cat /dev/vide16 > sample.mpg .. ctrl-c
dd if=/root/sample.mpg of=/dev/video16 bs=64k
# Now put the saa7127 back in, enabling the output
rmmod saa7127
insmod saa7127 enable_output=1 output_select=1 pal=1
# Finally the framebuffer
modprobe ivtv-fb
Then I modified it a little (will post this one, when I have access to the
MythTV machine again,
And tried,
> Fix it for video output with
> ivtvfbctl /dev/fb1 -globalalpha -nolocalalpha -alpha 0
This works great !!!!!!!!!! Thanks a lot so far.
> and for framebuffer (X output) with
> ivtvfbctl /dev/fb1 -noglobalalpha -nolocalalpha
But this leads to the double picture I described... :-((

If I the start the Mythfrontend nothing changes but I also have a "double"
pciture with the frontend (Yes I changed the gui display resolution to PAL-TV
720x576, but it wouldn't help either)

I have tried this one too, no change....

So your advising me to try the ivtv-0.1.10pre2-ck100b?
Would this download contain ivtv _and_ ivtvdev files?
Still a little bit unhappy, but I can at least see some ligth at the end of
the tunnel.
