The previous timings made Andrew on my card and it's  working fine, but not on 
Markus Nexus.

The card could only tune to one frequency at the start of all DVB application. 
With the longer msleep the problem is solved, only the tuning is a little bit 
slower but all applications running fine now.
On my card the new value is fine, too.
I've checked it with czap, dvbscan and vdr.
Markus with dvbscan and vdr.
The "Patch" is just changing the "10" to "100"
