Windows Movie Maker Question

This may be a wild stab in the dark, but is there anyone out there who has any knowledge about Windows Movie Maker?

I have edited a 15 minute movie*, and would like to save it in a DV video format from the software (as this will be the best quality output to convert and burn to DVD).. However every time I try to save the movie, the program seems to throw a bit of a fit, and ends up generating a 18 gigabyte file that has a running time of one hour and twenty six minutes!?!?  Now the original (unedited) footage I originally imported from the camcorder is only 22 minutes long, so quite where this mysterious hour and four minutes have come from I have no idea??

I have tried saving the project under a different name and selecting a different destination for the movie, but the file that gets output is still 18 gig in size.  This is very annoying.

If it turns out that I cannot output a DV AVI - what's the best file format available (from the non-Media Centre version of Windows Movie Maker) in terms of quality? 

Alternatively is there any alternative packages that can do the capture from a DV camcorder, editing (including digital wipes between edits for that truly George Lucas look between scenes) and burning directly to DVD?

Any help or advice would be greatly appreciated..

* - Aye, this is a very "proud Dad" movie, but I care not as she looks very cute all the way through and her grandparents in Spain will be very pleased to receive the DVD (as they have not seen her since June) if I can ever get the sodding thing to work...

Ciao!

So a fond farewell to the World Cup, you kept me entertained for most of the month and whilst the end result leaves me feeling slightly cheated (I cannot put my finger on why exactly, and it's not something as simple as England not winning it), the competition certainly had it's memorable moments.

And a temporary farewell to the good Doctor.  What an end to a series that was, I felt exhausted by the end of it all. 

Weekends won't be the same for a good while now will they?  Seems an age until the Community Shield brings football back to the fore.

Still, I have the odd behaviour of "Windows XP Movie Maker" to keep me amused for the next few weeks, as I play the "Guess when it's gonna crash" game, or (alternatively) the "Try and work out why it generated a 18Gb file for 15 minutes of video" game.  At some point I will get my directorial debut onto DVD, but it questionable as to whether I will still have hair left by then!
