I can't really see any difference with pic quality between Live TV and broadcasts although I agree with previous comments regarding being used to VCRS though..
Probably looking too closely and trying to find fault! I still have analogue cable in the bedroom so if I am in any doubt about pic quality I just watch that for a bit and then remember how s***e it is! then watch the pace again
The playback VOLUME though is definately not as loud as live broadcasts for some reason... even the missus noticed it! I have my pace vol locked on full and play through AV amp so just have to crank the amp up a bit...
