MPA Decoder Filter

[observer_11]

After much hair pulling I discovered why DTS is not being passed to my AV receiver when playing back 720p mkv files. The problem is the MPA Decoder Filter is automatically included in the filter graph and if I remove it and connect directly to AC3Filter I can pass thru my DTS and everything seems fine.

Anyways, in the config I have set AC3filter as my HD audio codec but in addition to AC3filter this MPA Decoder filter is automatically inserted. Anyone know why this happens, what this MPA decoder is doing, and more importantly how I can tell GBPVR to NOT use it as part of the playback?

GB-PVR only has a say in the decoders used when playing .mpg or .ts files. With .mkv files you'll just get whatever the system default decoders are.

To experiment, and produce the same results as GB-PVR, run GraphEdit and select the 'render media file' menu option, and select your .mkv file. To change the default decoders you'll need to fiddle around with filter merits etc.

OK thanks. Just re-enforces my theory that codecs are evil.
