Sounds so easy when someone else has thought it up eh Isaac?
Rather then slamming everyone for even bothering to come up with ideas, or decreeing something as not worth it because YOU don't see the value, I would think it'd be more constructive to follow the path of the kernel : put up or shut up.
The code and the result will speak for itself.
To have a petty argument about what a PVR is and question why someone would want to watch live TV _without_ a buffer, was amusing to say the least. (it's called buffer-while-paused-only) and it works very well:
1) - go live, 0 buffer
2) - hit pause for a commercial / whatever
-- myth starts buffering
3) - hit play, ff, skip .. whatever.
