[vdr] 1.3.18 clearing transfer buffer to avoid overflows

[Rainer Zocholl <UseNet-Posting-Nospam-74308-@zocki.toppoint.de>]

While recording 4 channels i got massive bufferoverflows
when viewing the recorded channel

Stopping one recording does not help
Stopping the second recording does not help either

recording of the 3 timers worked with 1.3.17 flawlessly.
The only difference to day: i added a fourth timer.

etc..

This causes sound to be "stagged" too, of course.


i have 3 DVB-FF so the load shouldn't be so high 
(AMD Duron1800 @1300MHz, UDMA on ;-))


Is there an EASY way to get an overview how the channels
are distributed over the cards?


too lrc commands are not immediately accepted.
