4 MBit/s is the MPEG2-stream, but at the V4L-device you have to grab the
complete, uncompressed video!

The netto-rate is about 3.5 MByte/s or 8 MByte/s if you have NICs with on
cache/CPU.

Yes, but I'm no C/C++-programmer. That's why I wasn't able to do it yet.

Klaus Schmidinger thought the same about VDR ...

VDRADMIN is a nice webinterface to handle VDR (only cutting is not
available).
