Best Converter?

So I am trying to figure out what is the fastest .mkv converter out there. I would like to convert to .avi. I used to have a great converter that converted the movies within an hour, but it stopped working and I forgot what it is called now.
Currently I use Xilisoft video converter. It takes forever to convert a single movie, sometimes up to 4 hours. I use an older desktop for downloading and converting, but it still isn’t that weak since I upgraded a few parts in it.
What converter do you guys use?
Answer #1
It’s always going to take some time to transcode movies as it is very CPU intensive..
You could try Freemake Video Converter, also Avidemux. (both freeware).
If you want to watch those .mkv movies on a TV, then it is best to use a media player so you don’t need to convert.
Most .mkv movies are HD, 720 or 1080p, so it is an advantage to be able to view them in their HD format..
Answer #2
WinAVI is the best in my opinion in terms of output quality and speed of conversion
Answer #3
I use Xilsoft it takes 10 mins to convert an AVI to MP4 for ipad, I suggest you look at your settings or see what else is running in the background. I find Xilsoft so good I actually pay for it!!

I’ve seen some people did a comparison about the conversion of the software on the website, and the famous xilisoft has a high ranking. As when you convert a video to another format with the different codec, then the videos will be decoded and encoded in the conversion. And this working will occupy CUP and even GPU.
