MKV to AVI Converter is a useful tool that can handle a variety of video formats, not only the ones included in its name. Thus, it can also encode other video extensions (e.g. MPG, ASF, WMV) to MKV or WMV, as well as split and edit output files (e.g. frame rate and size).

The user interface is plain and simple. You can open a video (the "drag and drop" method is unsupported), set its output format (MKV, AVI or WMV) and output destination, configure the audio and video compressor, and also start the converting process by using the controls on the main window.

MKV to AVI Converter requires you to provide it with various codecs, decoders and encoders installed on your system because it doesn't carry any with it.

Unfortunately, although the software kindly guides you to a website where you can download a codecs pack, some video files cannot be encoded. An error pops up but it doesn't actually point out the cause of the problem and the software doesn't offer any solutions.

Moreover, the program crashes or displays an error message every time it cannot recognize a video format (which happens many more times than you'd expect).

MKV to AVI Converter uses a low amount of system resources and has a help file (which can be improved), but you never know for sure if it will successfully encode your video files or not.

To wrap it up, you may give it a try but do not rely on this program as your only conversion tool because things might not go as planned.
