Simple editing of WMV files?

[terrypin]

I make the occasional brief WMV file using 'movie' mode of my digital camera. These play on my PC in WMP or (with reluctance) IrfanView. After browsing here for quite a while, I must say I'm a bit bewildered. Can anyone please recommend some simple-to-use software (preferably freeware) that will let me perform some or all of the folowing basic operations on my WMV files please:

1) Change the orientation, i.e. from landscape to portrait or vice versa

2) Remove unwanted sections, at least from the start or end.

3) Edit the soundtrack

4) Convert the WMV to some more universal format like MPG.

Thanks.

I was mistaken about the file format: my Sony DSC1 Cybershot creates MPG movies.

After further research I've found that I can use MS Windows Movie Maker.

I'm now stuck with the rotation problem, about which I've posted separately. Hopefully someone here may be able to help me fix that please?
