VLC video converting for Xoom I have a mkv HD video and I'm trying to watch it on my motorola xoom. I found some players but none of them was good enough to play my video smoothly. Then I read on the internet that I need to convert my video to mp4 in a certain format but I can't find a free converter that can do that for me.

So I found out that VLC can convert the video for me but it takes too much time. I would like to know if someone have already converted hd videos using vlc and it played fine on the Xoom or if you have a better alternative free solution (I'm on a mac, so it'd be good to have a solution for mac).
You can try Handbrake - a multiplatform open-source video transcoder. It has quite user-friendly graphical interface, and supports different device profiles (you can roll your own as well). As to what settings to use on your Xoom: Here someone managed to find the correct settings to make their Xoom play the transcoded video. 

Some extra googling would probably give you additional information how to set the device profile in Handbrake -- seems a lot of people are trying to transcode video on this tablet.
