I'm converting some movies and it's the strangest thing. I have queued 3 movies all in .MKV format to do ATV 5.1+2.0 and one of the movie churned out as .MOV while the others are .MP4

Can someone explain the discrepancy?

I don't think the app can convert MKV to MP4. I just live with it, seeing as they both work just dandy with iTunes and Front Row. It's obviously something to do with the MKV format (or it's compatibility with Visual Hub), but I don't have a clue what.

AS long as they play on my ATV I'm kosher but still confused.

Well I think an explanation wouldn't be too likely to come from the developers of it, seeing as Visual Hub and iSquint are now discontinued. :(

Most likely going to depend on what type of audio was in the original source file. If it was an ac3 track then visualhub would produce a .mov file. It is only able to create appletv files with ac3 tracks in the .mov container. However if the original file contained a dts or a different audio source then it creates a single downmixed audio track, which it is capable of muxing into a .mp4 container. The downside to using visualhub to create a file with an ac3 audio track is that it uses the .mov container which can't be fully tagged with meta-data. For instance you can't add mpaa ratings to a .mov file created in visualhub, as well as some other tags I believe.

For future compatibility, and current development familiarize yourself with handbrake (especially the current development builds), maybe harder to figure out at first but is capable of producing excellent looking/sounding files all in a correct .m4v container. It's also being actively developed so improvements are being made on a regular basis.
