Hi Kirby and all,
I'm not sure if I'm adding something useful or intersting at all, 
because I'm
currently following these threads only very superficially. I just wanted
to demonstrate, that the use of a simple canvas3.py - which uses Tkinter
directly -  can also speed up your ultra slow TV considerably.

See attachments. (nks2.py has only the import statement and the last
line of the next() method  added to nks.py. You can delete the last one
if you don't want to watch the pyramid growing)

Regards,
Gregor Lingl
