[G5] Video joiner

[Jerry Bunn]

I have downloaded a few movie clips.  Because of the size, the movies  
have been split. They are intended to play in Window Media Player.  I  
can play the first part, although it only plays to the half way  
point.  But I can't even start the second part.  I think that in  
order to play both parts I need to join them into one.

Is there a Mac version of a software program that will join these?  I  
can find several programs for PC's but not for the Mac.

Using 10.4.8 on a G5.

Thanks

Jerry
