On Gentoo there is a USE flag that adds a patch to vdr that solves this problem in one way.
package: media-video/vdr-1.6.0_p1-r1
USE flag: cutterlimit       : Limit IO bandwith used for cutting

Hi,

I have updated my vdr:

Old: Celeron 850 MHz, 256 MB Ram, very slow but silent PATA disk,
Debian, vdr 1.4.x (e-tobi)

New: AMD Athlon X2 2,1 GHz, 2 GB Ram, standard SATA disk, Ubuntu, vdr
1.6.x (self-compiled from e-tobi's repository)

The hardware should be much faster now, but vdr turns very slow and
unresponsive whenever it cuts a recording in the background. vdr reacts
to a button on the remote with notable delay.

(I don't remember this behaviour with the old vdr setup.)

Any idea where to look for this issue?

Thanks,

Hanno
