BleepingComputer.com: How to make an .avi file smaller

I've downloaded a movie that I want to watch on my TV, but I can't write it to the DVD because it's too large. It is 6.90 GB, but I need it to be 4.5 at most. When downloading the movie, I got many .rar files that I had to extract. Is there any way I can split the extracted movie into 2 parts, so I can write one half on one DVD and the other on another DVD, or do anything with it, so it fits on the disk. I am using KMPlayer and VLC media player if that helps. The file is 1:51:01 hours long. (1hour 51mins and 1 second )
Don't ask me why I downloaded such a large file. It's because I couldn't find the movie anywhere else and had to download the huge one.
Thank you
P.S. I don't want to download any extra software.
P.P.S. It was originally a .mkv file, but is it ok, if I renamed it into .avi, because that is the format I always write the movies onto DVDs in. Will an mkv file still work on the TV, or will I need to change it to .avi?

Give this a try:

1. A .mkv file will play on your TV, provided your DVD Player supports the format.

2. Have you ever considered encoding the movie(video) into AVI, using either the DivX or Xvid codecs? You're looking at file sizes ranging from 2GB all the way to 700MB for a movie, the former offering the best quality and subsequently going down the scale.

700MB is not bad either, just that it won't scale very well on a 32"+ LCD TV, due to the low resolution and high compression factor.

Mind telling us which movie this is? ;)
