There seems to be a problem with DVR on the IR in performer 2.1.

This can be simply demonstrated using perfly. Set up your IR to do
2++at++1280x1024_60. Log in etc. Run perfly -c 2 -V 1 afile.flt . The left
channel (channel 0) output is scaled (by using the up and down arrow
keys) but the right channel (channel 1) has its image scaled down but
does not then resize properly. You can turn the stats on to show the
effect if you haven't got a database loaded.

I tried modifying the vchan.c demo in /usr/share/Performer......
to output two channels or even select channel 1 for DVR to happen on.
It seemed to want to perform DVR on channel 0 no matter what I did.

It's OK if you want one channel to be DVR'd.

Does anyone know anything about this ?

Thanks,

        Clive.
