Hello,
This is my first Linux experience and I'm quite lost.
First a short summary of how I got here, I got this nice Canon HD video camera as a present for my birthday. The software for editing the video that came with it is incompatible with my 64 bit Windows 7 system. There are some nice commercial video editing software, but quite expensive, so looking around I found there are even nicer software, free, but only for Linux. But I also noticed there was a way to try them with these "live cd", "distros" and stuff like that. There is actually a plethora of these and figuring out how to approach is quite daunting.

The first I tried was the Kdenlive here:
http://www.poure.com/kdenlive/debian...090702.x64.img
But got stuck when it apparently does not recognize my Nvidia 9400M graphics card and the boot never finishes.

So then I tried dyne:bolic, hoping to try Cinerrela, but no luck there either, boot never finishes and I don't know why.

So then according to this site:
http://cinelerra.org/getting_cinelerra.php
Knoppix supposedly includes cinerrela so I tried that next.

Now, for the first time knoppix did boot!. I got it the following way, downloaded the universal USB installer and chose koppix fron the list, downloaded that and it got installed in a 4GB USB pendrive.
It does not seem to contain Cinerrela though.

So my first questions are:

1. Knoppix does not seem to be taking full advantage of my display. It is capable of 1920x1200, how can I change that? there are no choices but the default.
2. During boot I chose to allow 2000 MB for data, but no matter how many times I try to setup the internet connection it does not seem to "Stick" and disappears. I have a wired connection, it's not working with knoppix, how do I set it up?
3. Once I get that running, supposing I download Kdenlive,Cinerrela or whatever other application, how do I install them using this USB system?

Thanks for any help.
