I'm sorry, but you seem to misunderstand what that was about. It's not a 
contest really, I was merely describing my situation in as much detail 
as possible. It sometimes helps, you know?

If I watched all 1500 channels I can tune with my basic setup, I 
wouldn't do anything else. Even these 66 hand-picked channels are much 
more than I can use. As for SchedulesDirect, I know them quite well, 
they were an inspiration for my new grabber. Not enough info for my 
taste though, sorry. :) The mentioned details naturally meant the 
volume, not the variety of XML elements. But next time, I'll try to 
recite the *complete* subset of implemented XMLTV DTD for you.

There isn't anything like SchedulesDirect in my area. All grabbers are 
pitiful. Maybe when you finish your own multi-threaded HTML parser able 
to dig up the tiniest bit of information from regular human-readable TV 
sites using complex algorithms, data structures and logic, you'll also 
have a special place for it in your heart. But then again, maybe not. I do.

PS: I especially enjoyed your enquiry about my family's recording 
habits. When you understand the fundamental difference between Program 
Finder approach and Listings approach, feel free to truly rid the world 
of us bizarro viewers.


Again, icons helped and everything is super fast again. Thanks to all 
with helpful and constructive suggestions! See you,
