[mythtv-users] PAL-I problem

Hiya,

I have just about finished setting up my own MythTV PVR but for one small 
niggling problem and I can't seem to be able to get round it.

The set-up uses 32-bit Kanotix (2005-03) running on an AMD 64 300+, with 
MythTV 0.18.1 debs provided by http://dijkstra.csh.rit.edu/~mdz/debian.

I have a Hauppauge Primio WinTV PCI-FM (cx8800) card and it works great when
watching LiveTV. However, as I live in the UK which uses PAL-I I need to 
manually set "v4lctl setnorm PAL-I" when I first start-up mythfrontend.
That's no problem when I boot up the machine as I just stuck it into a small 
shell-script in the .kde/Autostart directory.
So watching TV is no problem. However, I have yet to manage to get a proper 
recording. MythBackend insists on changing the PAL norm back to BG
and so it starts recording the picture ok but obviously not the sound 
(effectively it just records white noise/static due to the difference in 
audio channels in PAL-I and BG). 
I have a small cron-script that checks every minute the status of v4lctl to 
see whether it needs changing back to PAL-I and that works ok, eg it changes 
it back to PAL-I. However, when it executes during a recording, MythTV now 
records the correct sound and image, However, the image is not fullscreen 
anymore. I tried calling "v4lctl fullscreen" as part of that cron-script but 
it had no effect.

Has anyone else had that problem? And also, does anyone know why PAL-I is not 
an option in the MythTV set-up?


Any help would be much appreciated. It's the last missing piece (but sadly the 
most important one...)

Cheers,
 Steve
