Err, I do have this pause, 1-3s maybe, normally at the hour while
watching live tv. Had not considered complaining about it...

I am using xfs, and even though I have two receiver cards, I am
normally only using the dvb-s card.

It seems that the file system is not determining this, at least it is
not the only factor.

I am using a remote frontend for watching, over a 100MBit network. The
frontend boots from a cf card and mounts everything that did not fit
on the card via NFS from the backend. 

The backend uses a dedicated pata disk for recordings, this disk is
hdb. hda only carries grub, boot, windows, a rescue linux and the mp3
collection (i.e. it is not used while watching live tv). The backend's
os is running from two disks on a pci ide card. 

In the Athlon XP2500+ PC I have two dvb cards, one ide card, one scsi
card,an additional USB2 card and the agp graphics card - the pc is
full. I had stability problems until disabling apci. 

Maybe there is an irq problem responsible for this delay? Just a
thought. 

I am waiting for reiser4 to get included in the maintstream kernel, I'd
love to see this fs.
