a trivial solution would be to tune into the channel when recording
should take place according to epg, and listen for the vps, as the
recording would take place from then on without vps that sounds ok for
me. this would miss events when a show starts early, for these cases i
don't know a propper solution, do you know if this is common practice by

hm thats a tough one.
<wild guessing mode>
why not start recording accodring to epg, and chop of the beginning
when receiving a correct vps? as you mentioned before stop recording
because of a vps event would be straitforward problem solved?!
