If you stream the HD from Netflix, 1.5 Mbs DSL won't cut it.
I just got back into Netflix last december after a 10 yr break. Tivo sufficed for a while. Then I started spending $9/BR at Blockbuster and it no longer made sense.
I've tried the Netflix streaming on my HD Tivo and it's actually decent. (I have the 3 Mbs DSL BTW). On my Mac it seems fine, better at work w/ the faster speed. Waiting to try it on my hacked Apple TV running Boxee. Although Hulu on that box works out fine just for the kids' stuff.
Tom, you might check out the CES announcements. I seem to recall some players (at least some TVs) w/ Netflix support.
I was at Macworld and saw a bit of the Slingplayer for iPhone. Can't wait for that one. The Slingplayer Mac HD looked much better than the current version as well.
It may seem like I watch a lot of TV... Kinda. But I probably more time tweaking/hacking to have the ability, versus actually watching what I enable.
