I voted none.. for two reasons.
One, I am positively disgusted with the freebie TDN BD that came with the PS3, so much so that I want to forget I ever had it.
Two, I did not find any movie worth buying on BR so far. Well, I was tempted with Casino Royale, but not enough to buy it.
OTOH, I own Pitch Black, Riddick, PoTO, Batman Begins and DVE-HD on HD-DVD. I could have done without buying two of those discs.
I might buy The Matrix Trilogy pretty soon, and will definitely buy Lost and Alias collections when released on BD. Till then, no cigar.
I do rent a lot of BD and HD-DVD movies from BBO and Netflix.
