I was doing it with HD-DVD. With BluRay, I'm not so sure. There's hardly a competent player that isn't the PS3. There's far too many MPEG2 titles, many of which are on BD25 discs. Not to mention mediocre special feature support, and a menu system equal to that of the old DVD standard, and I still can't warm up to BluRay.
So to answer the question, I was for HD-DVD, but I'm not yet ready to do so for BluRay. Maybe if they get their stand alone players straightened out I can consider it.
