Thank you for replying

Absolutely right. And then EventCmdRecStarted calls:
cd /home/mythtv/bin/hdpvr2;./HDPVR2-testApp -f %DIR%/%FILE%

and then HDPVR2-testApp creates and starts writing to the file, provided 
%DIR% and %FILE% are valid, which you can tell by the log %DIR% isn't, 
although mythtv already determined it, also by the upper log.

Everything else is irrelevant.

Also, don't forget this works with LiveTV.

Thank you for the pointers, I'm sure I'll have to use them if this bug 
is not patched, which I'm trying to avoid given that the right approach 
is so simple.

Forgot to say that I'm on 0.27 fixes.
