Need Help Badly [Converting & Cutting .MKV/.AVI]

Hey,

Well I have a portable HDD and I normally put all my stuff I download like TV programmes from america and stuff and films onto it than watch them through the PS3 by plugging it in their and watching them on big TV but I downloaded a blu ray and tried to put on their but because PS3 has to be FAT32 when I tried to move onto portable HDD it said the file was to large and it was also a .MKV so it had to be converted anyone know how I can split the MKV into half than a good and fast video convertion software so I can change them to .AVI and watch it on PS3.

I am going to do some google searching myself and find some stuff but thought I'd ask here as well incase anyone knows some really good software or method.

Regards,
Berch

I hear this software is good, but i know nothing about it and have never used it. http://www.mkv2vob.com/showthread.php?tid=1

This is the best program I know of for converting MKVs for Xbox 360 and PS3 - don't know if it can do splitting though. Make sure you read everything because you need some extra software to use it :)
