yea it does do 4hrs of video easy lol
remember you probably using normal mode for compression on that tv ep.
Does great job. if you ask me for dvd rip or some thing. (usually one move per disk of course.) most movies 1.4GB now days.
it handles it pretty well if you put conversion setting up to highest mode
under the encode option > quality highest.
TV eps don't decrease in quality much. hence why you can fit alot on to dvd with out any problems.
but if your talking good quality DVDrips and stuff then of course your gonna hit issue
Edit: why temp its TV shows? you can't get any better unless you buy the dvd.
or download HD eps.
Most people aren't bothered to much by quality as long as it is respectable its generally good. i have HD TV so standard stuff doesn't look as good on it anyway
