You've got the wrong terminology there buddy. Part 2 of the MPEG-1 specification is indeed for video and part 3 is for audio, but part 3 and layer 3 are not the same. The MPEG-1 Part 3 audio specification includes three layers of audio formats, layers 1, 2 and 3 â each one building upon the other. Thus, layer 3 includes all the elements of layers 1 and 2 plus some new stuff. This is actually a bit inefficient because of the layering, but it was ultimately decided to implement the specification in this manner to allow for the greatest compatibility. The OGG audio codec is actually very similar to MP3, just without the layer 1 and 2 compatibility â hence it is marginally better than MP3.

MKV has nothing to do with your encoding/transcoding times. It's just a wrapper, or container. What governs your computational time is what's inside that wrapper. Admittedly, most MKV files on the web contain heavily compressed H264 video streams, which are very resource-intensive. But, that's not MKV's fault. If the MKV file were to contain an equivalently long and resolutioned MPEG-2 stream, it would be much faster to convert.

Also, they are usually at a better quality than those shabby .avi's (of course, all my .mkv's usually say 720p so that's probably why xD)
Oh, also. VLC laughs at those codecs! In a smug, french way. No-ho-ho-ho!
