Could you post that patch?

I've only one or two full-featured DVB-S-cards in that VDR-box.
So there will be only one record process and a second record or replay
process.

I'd like to set VIDEOBUFSIZE to 15 (only 64 MByte) RAM.

Are there any other processes than record/replay using VIDEOBUFSIZE, which
could flood my RAM?

Thanx
