In Zoom Player you can tell which decoders are being used and you can also specify which decoders to use. It also lets you open ffdshow while playing a file.
If I play a divx video with mp3 sound it shows that ffdshow is being used. When I open ffdshow it shows info. When I open ffdshow when a divx file with ac3 is playing it does not show any info.
But it doesn't really matter because even when it does show info, all it shows for the output is 'spdif'. So it doesn't help me troubleshoot why I'm pnly getting stereo when playing 5.1 ac3.
It WILL show the source audio i.e. AC3 - 6 channels audio.
AC3 and DTS is usually stored (xvid/divx) as mp3/448kb stream.
Mine says 48000Hz, 6 channels 448kbps ac3
Also make sure that you are using ffdshow-tryout for Vista
Then why DON'T I get any info? :)
I'm using ffdshow_rev979_20070301_clsid

Like i said - ffdshow tryout...Go to : http://ffdshow-tryout.sourceforge.net/ - click on Download for Vista.
This is the one you need.
Before you install - uninstall your other codecs/ffdshow
Sorry you are using that one - didn't know there were a new release version..
Then if it works in some files - and doesn't in others - then it must be something specific.
Try with some more files - and see if you can spot a pattern (like it's only xvid files - but divx works etc.)
There apparently is an issue with Vista's DRM and DTS/AC3 directly passthru. Because of the new sound hardware layer within Vista - no program can directly "talk" to the hardware or pass anything around Vista's DRM.
Its the same issue with Video/MPEG2 decoding and hardware accelleration. It'l work for some while others are stuck.I use an external Creative NX (USB2, COAX and Toslink) and it works perfectly - but for others it might work differently depending upon how the drivers "behave" within Vista and the DRM sound layer.
Microsoft solely decides if a hardware device (and it drivers) is allowed to talk directly to the hardware and circumvent the DRM issues that the program might be playing/streaming/copying.
