converting files to avi

I can watch all the file types I download on my computer without any problems, but if I transfer WMV, MP4, or FLV onto a memory stick to watch on my TV through my DVD player, It will only play AVI, or MPEG, is there a way I can convert these unplayable files to AVI files for free, or will I have to buy a program to solve this, as money is a bit of a problem at the moment.

Thank You

You will need to transcode the files, or at least the video streams within them. There are many video converter applications on the market for doing this. One worth looking at is from WinX, q.g.

Take a look at our Guides and Tutorials forum, for a lot more information about doing this.
