[vdr] vdr-1.3.13: driver buffer overflows

[Reinhard Nissl <rnissl@gmx.de>]

Hi,

while debugging a different issue I've discovered the following log entries:

Some additional information:
- Channel 987 is Euro1080 (HD1) and I would expect them to broadcast an 
encrypted stream at the moment.
- CPU load is high (~ 64 %) since 20:44:29 and caused by process vdr[25979].
- CPU load reaches maximum (~ 99 %) at 20:51:59 which is caused by processes 
vdr[25979] and vdr[25980].

Does anybody have an idea what's going wrong here?

Bye.
