Yes, there is a huge difference! "nice" only changes the lenght of time the 
programm could get the CPU. A higher scheduling priority is a side-effect, 
but this does not make sure that the process gets the CPU whenever he needs 
it.

My scheduling method does that. With this kernel-patch the scheduling of VDR 
is (nearly) independent of any other task. That means VDR can not be 
disturbed by other programms (even if there are lots of CPU- or I/O intense 
processes).

BTW: You can also set the nicelevel with vdrrun. It is the first parameter.
vdrrun [-nicelevel] command [arguments]
On my 133MHz box I use a nicelevel of +5 without problems.
