I think the problem is somehow connected to the CI+CAM giving a delay
which Myth cannot cope with. Unfortunately all channels are encrypted on
my cablenetwork, so I need the CI.

Setting a delay is also possible with 0.19 but it doesn't solve the
problem. When it fails it gives the following message in frontend
2006-09-17 14:11:34.349 NVP: Prebuffer wait timed out 10 times.
file (fd 16) when opening
'/mnt/store/mythtv/recordings//2512_20060917141128.mpg'. 2 retries
The buffering to the file hasn't started and is never going to anymore.
I need to find out how to increase the backend logging to find out what
is exactly going wrong.

I'm using kernel 2.6.17, but with experimental dvb-drivers, because the
stock-drivers won't work with the CI+CAM yet. For reference this is my
relevant lsmod output:
