Australia is not the only country with abominal schedule info. The 
commercial broadcasters in the Netherlands also have a tendency to  give 
schedule info which is close to "we intent this, what we do is something 
else".

I started with abusing the pre-roll / post-roll. Results were most 
certainly not to my liking:
- i never could know when the recording would be recorded
- i had several very surprising results (cut endings, which i consider 
to be worse than lost recording)
In the end i have taken care to have extra tuner capacity, and at the 
moment i consistently add at least 10 min to every recording when 
scheduling this recording.
1 recording schedule at the moment has 1 hour extra time, as the 
behaviour on that Belgium channel is abominal at the moment. And missing 
the end of a thriller like series is really irritating.

Option 2 would ease my life considerably.

Face up to it. Soft scheduling will still result in unexpected 
behaviour. Spend 50bucks to get an  extra tuner and spare yourself the 
disappointment.

Rudy
