If you have no money, then get a cheap PC and then download and instal ubuntu linux (it is very easy and automated and doesn't fill you HD with crap you don't need) from here: http://www.ubuntulinux.org/

then get cinelerra from here:
http://heroinewarrior.com/cinelerra.php3
also free.

Virtual dub from doom9.org (You can run it under windows or under linux using WINE..here http://www.winehq.com/) or
http://fixounet.free.fr/avidemux/ which is a virtual clone of virtualdub for linux.
both are free

You can use GIMP for stills editing, it is much like photoshop and is entirely free and is installed by ubuntu automagically.

Don't be scared. Ubuntu looks a lot like Windows except doesn't crash. I have literally NEVER had Ubuntu or Debian crash, and I have been using debian for 10 years - not one system crash - ever.

So no more excuses people about the money required to get into this stuff, ALL of the above is 100% free and doesn't need a beastmaster PC to run.
