I've decided to test some of these titles to see if they seem to have the third HD encoding. To test, I'll stream them to the PS3 while running the realtime bandwidth usage monitor in my router. The router shows an average bit rate for 10 minutes worth; after running 13 minutes or so (to scroll start-up behavior out of the monitor's 10 minute window) if the average is up above 5 Mbps then it indicates the higher rate stream. (These numbers include unplayed buffered video, so they're higher than the numbers quoted by Netflix. The 3.8 Mbps stream will typically average 4.2-4.5 Mbps; the higher rate stream 5.5 Mbps or more--I've seen it be 6 Mbps+). See my posts
here and
here for some examples of this.
This test is slow and can only prove that the stream has the 3rd HD encoding; since there might be reasons why the average in the window I was observing never got that high, like fluctuations bandwidth available on my connection to Netflix' server, it can't disprove that a title has the 3rd HD stream.
I'm not even going to try to test the entire list; for most of it I don't care whether it has a high bit rate HD stream or not. So far I've only tested four, all of which happened to be SE Asian action films:
The Good, the Bad, the Weird,
Ong Bak 2,
Ong Bak 3 and
Red Cliff. I'm going to concentrate my testing on highly visual titles: the action stuff, Sci Fi, etc.
Does anyone have any suggestions? Stuff that you've watched on the PS3 that you suspected was 1080p would be most interesting.
In the list, I'm coloring the titles which seem to have the 3rd HD encoding
bold sky blue. It seems distinct and reasonably readable, without being eye-searing.
BTW, notice that I asked a mod to remove "(PS3 Only)" from the thread title, which has been done

. Thanks, Mike Lang!
