I suggest this to you. down load a large MKV file at least a gig.

Put it in winavi. Bitrate 2000, ratio 1280X720 (for wide screen), audio 320 and you'll see it will reduce it in half with very little loss of quality.

Maybe so, but what is the bitrate and codec of the incoming file, and what is the codec being used for the outgoing file? If the bitrate and codec of the incoming file are the same, then it won't reduce at all.
Those files you are downloading at that kind of size are probably encoded to a high quality (at a guess, 10000kbps and 1920), which means that yes you can most likely re-encode them to a lower quality with little noticeable loss (depending where you are playing them back), but that won't be the case with all vids.

I'm using Windows Vista. I record straight from TV and get the following;

File type: MPEG Movie
Image Size: 544 x 576
Pixel Depth 32
Frame Rate: 25
Average Data Rate: 244kb / second
