I don't care about the resolution of these clips, I blow them up to full-screen size and you can still make out whats going on (and I remember most of it anyway). Actually I prefer the low-res which means they don't occupy huge amounts of my small hard drive.
Surely if you upload episodes (just 1 or 2 will do, dosn't have to be all of them) it won't be any harder to upload clips and the whole episodes will be greatly appreciated. We won't have to complain about challange not showing them anymore - it will make a lot of people very happy I'm sure!

The clips seam to be in 34kbps which surely means that a whole episode will take up a mere 51MB of hard-disk space which is fantastically economical, considering even cd-quality MP3s are usually 128kbps.
Great site BTW
