I think your content numbers are maybe down by half, but there's likely not many more than 1,000 titles in either camp, and there are more in BR than HD, but really it's pathetic.
And alot of the disks that are out there are pointless on HD, Casablanca on HD? Errol Flynn's Robin Hood? C'mon!
If either wanted to makes sales jump releasing LOTR on either format equals 200+K sales there, same with Star Wars and Aliens franchises IMO.
Biggest mistake HD-DVD made was bundling Matrix instead of letting people buy it alone. It was one of the watershed DVD titles that made people buy players (the one for me was Top Gun), and likely would've sold a ton more if people weren't forced to buy the mediocre 2 sequels as well; $30-35 for the Matrix, sure but $80 for all three when all I want is one, forget it!
I see the difference between HD and SD, but the majority of people don't, so charging hefty premiums just kills your market and forces you to burden more of the start-up development cost on a smaller pool of consumers.
IMO BR didn't 'WIN' , if anything they just got a reprive from death, but their end time will come soon enough too, especially if they continue on with these myopic strategies that saw neither format grow.
As for the OTA-Cable, OTA is not heavily compressed, while cable usually is, which is why FIOS is usually better and closer to OTA (but you don't get VOD without some hardline). Alot of it really depends on where you are, if you have the OTA option that's nice, but some of us need one of the triumvirate of evil: Sat, Cable, DSL/Fibre.
