ISO settings and post production software

Hi all,
I am still new to the world of filming with the GH1 and I am still trying to get to grips with it. I am currently in the middle of filming my first short film and I have a couple of questions if anybody can help out with them:

1) What would be a good ISO setting for filming with the GH1? I shot my first scene yesterday in a room. I tried to give off the dimly lit room effect by setting the ISO to 100 (even though the light was fully on in the room). Playback looked fine on the GH1 but when I viewed it on my computer, the footage looked way too dark. I think I'll have to call back the actor I used and re-shoot the footage all over again in a higher ISO. The shutter speed I used was 1/60. Did I mess things up by setting the ISO too low?

2) The only film production software I have at the moment is Windows Movie Maker (due to financial issues at the moment) which is very basic and isn't compatible with the two video formats that the GH1 films in; avchd and mov (motion jpeg). I shot my footage in the 720 setting (mov. format) and then converted it to wmv. format so it would be compatible with Windows Movie Maker. However, when I converted it to wmv format, the footage looked terrible and lost a lot of its quality. The program I used to convert the footage is a free download called "Prism Video Converter". Is there a better video converter program (and free if possible) out there that will not cause the footage to lose its quality when converted? Am I just wasting my time using Windows Movie Maker and just save up and get better editing software? I was thinking that Windows Movie Maker may not even be compatible with HD video.

Any help or advice is appreciated. Thanks guys.

Somebody reported that sweet spot is ISO 320-640. I am satisfied with ISO 640 in low-light environment.
