Sony 2011 profile, this gets transcoded to mpeg2 but it appears at face value the same as all other HD videos that don't get fully transcoded.

It's because the h264 profile level is High@L5 despite what the header of the file states - see http://wiki.serviio.org/doku.php?id=get_h264_level

This is then transcoded in accordance with the first rule in the Sony 2012 profile (which the 2011 profile inherits).

How can you tell its level 5.1 ? It claims 4.1 which is why I was surprised to be transcoding...

Do you read the wiki ? http://wiki.serviio.org/doku.php?id=get_h264_level

1920x1080x5/256=40500 ==> Level > 4.2 this is not a 4.1 level

if there were 4 refframe, it should be a 4.1 level...

I have to admit I didn't full appreciate how the lv worked and was calculated. I do now so thank you.....

Being pedantic but I also want to to double check my understanding (I make this a level 5.0) :

1920x1080x5/256=40500 ==> Level > 5.0 as the 40500 exceeds the Level 4.2 MaxDpbMbs of 34,816 (but is less than the level 5.0 MaxDpbMbs of 110,400)

Oups,
Yes Maxbdp for 4.2 is 34816, so 40500 exceeds the level then, you are right level should be 5.0...
