The design of your blog is awesome. Really luv it!
VLC is a decent player to install on other people's systems, as I still hate getting phone calls over mundane issues like codecs.
Handbrake is the must-have converter, :hmm: besides I also love using WinX DVD Auhtor (

As for compression, I prefer 7-zip than Winrar...
