Update December 8, 2012: Based on information in later posts, Netflix has changed a few things. High/HD is now the 1080p feed using a new compression technique that allows a lower bitrate. Medium/HD is now the only 720p feed. X-High/HD is no longer used except for some older titles that have not been updated.

For the past few days, I've noticed something odd with Netflix. I'm using a WDTV Live Streaming, hardwired, on Comcast Performance cable (speed tests show 25/4).
Basically, some titles, "Star Trek: Enterprise", "Star Trek" [old series], and "Hell on Wheels" no longer go to X-High/HD. They max out at High/HD. I do get the proper 5.1 audio on ST and HoW. ST:E has always been 2.0.
I tried Will Ferrell's spoof "Casa de mi Padre", and it runs X-High/HD, as does an episode of "Louie".
The WDTV is the only device I have that supports X-High/HD and 5.1 audio, so I can't check against something else. I also ran the Vudu network test (I don't have a Vudu account), and it ran with the bar maxed out the full time.
I was just wondering if it's something odd about me, some of these titles, Netflix? Anyone else notice something?
