Certain MKVs playing at double speed.

[LocrEpinS]

Greets.
Tis my first post btw xD.

Ok. Well.. I've never had problems with playing video formats in the past so i've really never done any custom configuring of apps like ffdshow etc. So i'm quite clueless about it all.

The problem i'm having is that i've recently downloaded MKV files(anime) which contain H264 video and AAC audio. But for some odd reason when i play them, they're being decoded/played at > twice the speed (~65fps).

Here's the dump from mkvinfo.

I checked it to see if it would happen with VLC MP, and it turns out it works fine.

Thx in advance.

Latest version of ffdshow?
What do you use to decode the mkv container? haali media splitter?

I use haali media splitter for mkv decoding and coreavc for h264 and I haven't had any problems with most mkvs.

Edit: Ok, i managed to find what was causing the problem. It turned out to be the aac decoder. This is fault on my part since i used to install tons off little codecs b4 i started using codec packs.
