[QUOTE="jo16v, post: 416935, member: 81927"] I'd be interested to know how that turned out? I was just testing out Windows 7 (normally use XP) and found this to be the case with 3200HD and a x2 5000+ i.e. if aero is turned on all deinterlacing, SD and HD will be limited to Bob- I guess this applies to 3200 HD and all non HT3 processors (i.e. x2 7750 or Phenom). <<aero is turned off by disabling "Enable desktop composition" in system properties (right click my computer) - advanced system settings - performance - visual effects>>. Contrary to what has been said here, EVR still works when aero is turned off and will give DXVA on Cyberlink, Arcsoft, Elecard/Mainconcept and MPC decoders. You can get vector adaptive (best) deinterlacing with DXVA with SD material, but with 1080i HD material it reverts to Bob. What I have found though is the slider [B]doesn't [/B]always move, but if you have the CCC window up with the ATi flag waving, with vector adaptive on SD it should be very smooth, however, when you move to HD sometimes it stays on vector adaptive but the flag will instantly show jaggies indicating it has reverted to Bob even though the slider has not changed. [B]REQUEST[/B]: [B]Can anyone with a 7750/Phenom + 3200 HD do this 'flag' test this to see if you really are getting vector adaptive on HD- the ATi flag in CCC must stay smooth in moving from interlaced SD to interlaced HD. If it does not stay smooth with aero turned on, can you turn aero off following the instructions above and retest[/B]:thx: [I] [URL="http://i535.photobucket.com/albums/ee357/jacz3/ATideinterlaceflag.jpg"]Here is an image [/URL] showing smooth vector adaptive flag on left and Bob on right.[/I] Relying on the 'flag method' to prove vector adaptive is still in use on HD I discovered ffdshow can get round this limitation by using CPU decoding and passing the deinterlacing to the GPU.
