Thanks for this entry. It helped me to get my .dvr-ms and .ts (HD PVR) files to both play beautifully on my VMC setup. I did have an issue where the ArcSoft Audio Effect HD and the ArcSoft Audio Decoder HD did not seem to care what their merit was and insisted to be used above everything else. After I unregistered them, everything seems to work great. The .TS files are using the ArcSoft Video Decoder and .dvr-ms uses Microsoft MPEG-2 Decoder. Both use Microsoft MPEG-1/DD Audio Decoder for audio.

I don't like to disable filters because it can break the application that installed them (I still need to use PDVD to watch BR movies for e.g.).

In the complex case, the ArcSoft video filter needs to be there for VC-1 content, so manipulating merit was the only approach (short of explicit graph building) that would work.

Andy, good article. I've also been using GraphStudio as a replacement for GraphEdit and it is definitely a step in the right direction as far as usability is concerned.

Another great tool when testing codecs is Nirsofts InstalledCodec.

www.nirsoft.net/.../installed_codec.html

It allows you to disable/enable directshow filters. The benefit over changing merits is that the changes will take place immediately. If say you want Arcsoft to not be used simply disable the filter with InstalledCodec, reopen the file in GraphStudio and boom. It's gone. Want it back, reverse the process. I use this process a lot for testing multiple video decoders when Sage puts out an update. At the end I pretty much disable all the ones I'm not going to use. The biggest benefit is the time saved by not having to constantly log off/on to see the changes.

Regards,

Jeremy

Fantastic post! Hopefully many will read and also gain a better understanding as I did.
