After all that bad reports about ReiserFS i have to state:

I have a Maxtor with a 37GB ReiserFS partition working fine here with vdr, no 
problems (Tekram BX with only UDMA33 controller, i get hdparm rates of 
16MB/sec).

I use this partition for grabbing dv-videos via linux1394 with 3.3 MB/sec 
too. (that is several times more than vdr needs) It just went's critical if 
the partition is filled up to >91% (mainly because i store a lot of small 
files on it as well).

Is it possible that your hardware is buggy or some chipset driver broken?
