[linux-dvb] DVD playback support for VDR-0.85 on low-end systems

["Jean-Claude REPETTO" <jrepetto@francenet.fr>]

Hi,
I am trying to understand why the CPU charge varies from 50% to 0% on my
Pentium 200 MMX during a DVD playback.
With the "top" utility, I have found that when there are problems on display
and sound, the task "dvb_mon" takes a lot of CPU.

When there are no problems :

I hope it will help to improve the DVD reader. I can send a full report by
private email if needed.


Best regards,

Jean-Claude
