I dropped Netfix about two months ago and switched to Blockbuster. We don't have a way to view Blu-ray at this time (wife wants new counter tops before she'll let me replace the TV in the faminly room with something that will play 1080p) so we only get regular DVD's.
I had the two-at-a-time unlimited plan at Netflix because there are rarely any weeks that more then two good videos would be released. On those few occasions when more then two did come out I'd get two of the videos and the third would end up on long wait. I'd call to complain about the long waits (some would remain in my queue for a few months) and finally when someone I worked with who also has Netflix put a couple of my long wait movie titles in their queue and got them immediately while they remained on long wait in my queue I decided to drop Netflix.
I signed up for the free month of Blockbuster to test it's service (two at a time plan) and plugged in some of my long wait titles and got them right away. For new releases I get them two at a time. On those weeks where more then two new releases came out, I think I only waited three days to get the next new release.
I was always happy with Netflix until they started 'throttling' my account. I've been happy with Blockbuster so far.
