The PVR 250 interface is quite simple:
1. pvr250-setchannel - to set the channel
2. pvr250-setsize - to set the screen size (720x576, 352x288)
3. dd if=/dev/cxm0 of=tv.mpg ibs=1m obs=1m
I worte a little script, that helps scheduling the recording (via
at) and manages the recording (on my old box are some odds and
edges: NIC usage should be reduced during recording and sometimes
dd gets no more data).
I attached that script. I dont know, if it needs a license... If
yes, then it shall hereby be the BSD license or so...
Bye
Arne
