Did video recorders somehow pass you by?
I live in Belgium and built my own PVR. The biggest problems recording shows over here:
- getting decent program information (no XMLTV service available so you have to use a grabber and the information isn't always accurate)
- most stations decide on the fly to change their schedule/programming because of sport-events and other stuff
- most channels have no notion of starting on time so I have to program the PVR to start recording 5 minutes before the indicated time and record for an extra 10 minutes afterwards.... and still you get shows that aren't recorded completely.
As the original poster said; it's all about convenience. I can watch 1h worth of live TV in 2/3rds of the time when it suits me. I usually get home late from work so it saves me time and allows me to watch when I can.
