[CUBE] TV Recording

[Rob In der Maur]

Thanks Jeff for your view on this. What I also noticed is that after a 
reboot things are working much better; I mostly encouter the drop of 
frames during TV capture when I have my Cube running for several days. 
To me this looks like a memory problem: lots of apps might have leaked 
memory during those days and have not returned that memory; hence the 
memory I can use without swapping will diminish over time. As a result 
more swapping, slower machine.
Am I correct in assuming that leaked memory can only be released when 
you do a reboot?

cheers,
Rob
