4 trak traktor user considering mixvibes...has questions

its been a long time since i checked out mixvibes......i see there have been improvements
Ive been using traktor and I considering trying out Cross DJ and the video plug in since i want to do music video mixing....but i dont really want to get rid of the Numark 4 trak I currently have.....and im not a big fan of serato...so im looking for options
I have a bunch of questions......
a) is there one to one auto mapping available for the 4trak
b) on the full version of Cross DJ...are the effects post fader....ie do the effects fade out after the music is stopped or the channel or fader is turned off.....or do the effects end when the music is stopped or the channel is cut......for the demo....the latter is the case...ie no decay when the channel is changed or deck stopped...everything is abruptly cutt....I DO NOT LIKE THIS and this should be changed to provide proper effects.
c) is there a demo of the video plug in.....I want to see what Im dealing with before I decide to buy it
d) is there 1 to 1 mapping existing or in progress for the ns7II.....
e) is there a customer service number so I can be talked thru issues if i decide to buy the mix vibes package?
f) are there you tube videos that go into more indepth coverage of the softwear...so far Ive only been able to find very short video clips
