Vista compatible mpeg joiner where 2 clips have diff dimensions?

[wetcamelfood]

I have two mpeg clips with different dimension, so presumably one or both clips need to be resized and re-encoded either before joining, or as part of the join (preferably the latter to save me the step).

I used to use Womble Mpeg VCR for this which worked great but I had to buy a new tower which had Windows Vista and I can't seem to get Womble to work on this.

So can someone point out a Vista compatible tool I can get that will do this for me?

I checked the search section of this site and there wasn't a way (that I could find) where I could search tools on that criteria, this is why I must ask about it here.

Thanks in advance for the replies.

Or a free solution, reconvert the first clip using avidemux(with same settings as the other) and then join using avidemux again.
