I'm using declink sp to playback my comps on a broadcast monitor.
The truble is whenever I switch on the monitor icon Shakes slows down to 5fps. Why?
I found someone asking the same question here, but there was no answer:
[http://www.highend2d.com/boards/showthreaded.php?Cat=1](http://www.highend2d.com/boards/showthreaded.php?Cat=1),6,7,8,9&Board=shakeforum&Number=196991&Search=true&Forum=shakeforum&Words=monitor&Match=Entire%20Phrase&Searchpage=0&Limit=25&Old=allposts&Main=196991
ANY sugestions? please?

the answer from black magic is:
"Hi,
I think this is a limitation of Shake and there's nothing we can do
about it."
...so I guess, one have to relly on disk flipbooks to preview in realtime.
