Since my VDR is in the living room, i recently switched to a 100% diskless solution
and until now i was having regular freezes when recording a channel and playing back
a divx at the same time.
(system is linux based Debian Sid/PIII 1Ghz/VDR 1.3.36)

I, indeed, forgot to add "elevator=cfq" in the boot parameters (which i use on about all my
other workstations/server :), and up to now, it definitely improved things: No more
regular freezes (about every 10/12 sec), at last with the few channels/divx combinations
i know there used to be problems with.

So all in all, thx :) You made my day :)

Truly yours,
