Well I hear the Adobe video editing programs are rather good, however they are very expensive and I mean VERY expensive, however I do know that Adobe do test/trial versions of a lot of their software, it might not have all the features of the full versions but it might give you enough to play around with, probably worth giving it a go. My freind uses software called Sony Vegas Pro which he acquired, it is rather professional but he has told me that they do a 30 day trial. I hope you editing goes well and would love to see the videos when finished.
