It looks like something in your system is so slow that it
takes over a minute to remove a few files.
This is not normal.
My watchdog timer is set to 15 seconds and it *never* hits
whe I remove a recording.

Maybe it is your file system.
I am using the XFS file system.
Which one are you using?

I would test the problem outside vdr, i.e.

   time rm -rf /video0/Comedy/Die_Harald_Schmidt_Show/_/2003-03-28.23:10.50.50.rec

and see if it really takes that long. Here are the results on my machine:

% time rm -rf /video2/Science/nano/Die_Welt_von_morgen/2003-01-09.18:28.00.00.rec
0.000u 0.090s 0:00.11 81.8%     0+0k 0+0io 110pf+0w

(0.11 seconds to remove a recording)


A quick and dirty fix for you may be to start up vdr with
a longer watchdog timer delay. With the driver becoming
more stable nowadays, the watchdog timer no longer is as
crucial as it used to be...
