I have changed few things there, but none have helped... any specific suggestion please?

When trying Movies - DirectShow - TsMuxer I get an error on line:
if not CheckResult(WmsDirectShowConnectPin('Audio Decoder', 'DumpAudio', 'Out', '',
MEDIATYPE_Audio, KSDATAFORMAT_SUBTYPE_PCM)) then
Exit;

Win7 64

I've been using this new Buffer initially. Was even increasing Video buffer from 100MB up to 1GB. It looked like it made no difference. It hanged at full screen fast motion indefinitely always at the same time.
After turning Buffer off I am able to play movie with Video/Audio stutter.

Thanks for pointing me to the right direction... It could not load "CoreAVC Video Decoder" because for some reason CoreAVCDecoder64.ax & CoreAVCDecoder.ax were not registered. I have registered them with regsvr32 and it is loading fine now... I was hoping it will solve my other problem...

I am sorry if I am missing something here, but how can I get this profile working?
I have CoreAVC installed on my machine which is 64bit, but I see codec has both 32bit & 64bit versions. DO I need to copy over some files to WMS folder?
Thanks
