I'm sorry if some people get this repley a second time but some people 
sent me a mail
that they couldn't open the mail. I think it's this crappy Notes web 
client :-( I've changed to
Mozilla Mail. Hope this works now... Sorry again. And here now the 
original replay:

Hi Tim!

For your first problem I may have a solution. I've had a similar 
problem. First you should test
your drive speed eg.:
hdparm -Tt /dev/hda
If you your /video mountpoint is on a different drive try .../hdb or any 
other drive. hdparm prints
out two values. The second one is the one of interest. For the first 
time I ran this utility on my
hdd I've got an unswallowable value of 5-6 MByte/sec. In this case try a 
different UDMA hdd mode.
I've reduced it vom UDMA 5 to UDMA 3. Now it runs fine with around 30 
MByte/sec. You can
use hdparm to do this. I haven't the exaclty syntax here at the moment. 
Please look in the
manpage of hdparm or have a look at this page:

Subject: [vdr] Starting and Recording Problems

I've recently got VDR to work with my WinTV Nova (Budget) card and my
Hollywood+ (dxr3) card. I'm using it to watch terrestrial digital TV in
Oxford, UK.

It works well although I have two problems:

1. Every 5 seconds while recording the picture and sound are distorted.
This seems to correlate with the disk activity. I've tried this with the
preemptable kernel mode on and off.

2. When starting VDR I have to use dvdtune many times with different
frequencies to get all the channels to work.

These two problems are driving me mad and I would be very grateful if
someone could tell me how to fix them.

Regards,
Tim
