I noticed, that if I have mkv-files with ac3-sound and bitrates higher than 384, or DTS, then the playback on my MD (asrock 330, ion-platform) is quite choppy. If I remux the files to only ac3 with 384kbit/s, then they all play nicely.
So I was wondering, if this is a limitation in the playback-software or of my hardware. What do you think? By the way, when setting up this md, dts-test completed successfully.
