Can you describe the nature of the corruption?  Is it periodic or random?  
Is the video breaking up or are you seeing uniform distortion (e.g. colors 
out of whack)?

Starting with 2.6.18, commands to the mpeg2 encoder are determined by a 
new kernel module, cx2341x.ko.  That should be the only substantial 
difference.

Can you try the standalone driver in your 2.6.18 and see if the situation 
is any different?  I suspect it will be the same, but if it isn't then 
that's another clue.  To try the standalone driver just build it as you 
always would and simply rename the kernel-built pvrusb2.ko out of the way.
