Ok great, thanks for the pointer.  AFAIR when recompiling mga_vid 
this morning, depmod ran automatically as part of the make, make 
install process.  I certainly didn't run it as I had never heard of 
the depmod command before today (or the difference between 2.4 .o 
objects and 2.6 .ko kernel objects for that matter).

Heh, from what I gather the RH distros are suboptimal but I'd be 
nowhere without an organized, package managed distro of some sort. 
After a couple of years I am still just getting a grasp on some of 
the sysadmin esoterica as it interferes with my real work(TM).

Is there any reason not to run the 2.6.11 mga_vid.ko with a 2.6.10 
kernel?  IOW, is it worth figuring out how to fix the make file to 
have matching release numbers for mga_vid and kernel?

Nope, more of a case of not knowing well enough to run it in the 
first place as opposed to forgetting to do so.

Thanks guys, for your contributions to the mplayer/encoder software 
and for your lightning quick replies.  Viva free/OS software!
