interesting with Cyberlinks Decoder i get additional the Line 21 Decoder 2 loaded ? wasn't line 21 a Analog thing ?
This gets loaded on EVR Input 1 with Cyberlink DXVA
Filter: Line 21 Decoder 2
Pin: XForm Out

Hmm the Filter is in quartz.dll so it's coming from Microsoft i never saw this one on XP
ffdshow-quicksync though doesn't load it
http://msdn.microsoft.com/en-us/libr...=vs.85%29.aspx
yep it's the analog line that was used to transmit different types of data back in the Analog days (videodat,captions) seems Cyberlink loads it by default with some data strange or there is some hidden analog data in this Sony stream :P.

Seems indeed Cyberlink opens it by default now, i get it loaded for every stream
(never experienced this before seems to be new behavior)
PS: Egur i checked more carefully into the overhead and it seems without Quick Sync Recording the CPU usage is 10% @ playback with ffdshow quicksync and it increases it to 20% while Recording also Cyberlink DXVA Cpu usage increases while Recording but not by such a heavy amount just 2% more from 1 to 3%. So Recording with Quick Sync @ the same time currently seems to lower the efficiency of the Decoder somehow expected that also recording time critical stuff (D2D Browser Demos) shows a slowdown (low latency recording helps here a little).
Yup it seems there are more GPU resources allocated to the Recording that get lost for the Decoding and so CPU usage inreases
