O.K. here it is. This mode can be used on A540 and A5000 but it will only have
36Hz picture frequency. If clock your VIDC with 50 Mhz it will have 50Hz then
(I tried this and it worked fine except that 50Hz is still too flickery
for me).
If you choose 60Mhz for your VIDC it will have 60Hz but my VIDC didn't do this
(as I wrote in my previous article).

[code deleted]

How do you clock the VIDC with 60MHz? Do you just replace the quarz in the 
VIDC enhancer? Are there any known problems (apart from the one you mentioned)
that may cause damage to the VIDC?
The cooling of the VIDC could be done with a product called Icecap. I don't 
know if there is one that fits the size of the VIDC, though.
