Remove Youtube app limitations?

Not sure if it's possible to do this; in the UK some of our broadcasters put full shows on Youtube (demandfive, 4od) but these channels don't play through the Apple TV Youtube app as it seems to block out channels that have adverts on them. Likewise, these channels don't play in the XBMC Youtube app, as I assume it also doesn't access content that has adverts in it.

 

It'd be just lovely if ATVFlash could tweak the built in Apple Youtube app to be able to access these streams, heck, I wouldn't even mind sitting through the adverts legitimately before the programme plays.
