Have anyone tried to connect the N810 to a TV with the Nokia Video Cable (CA-75U), the same cable used on Nokia N95?

On this site, Nokia claims that the N810 3.5mm plug is a AV plug, which would say thet the N810 also can show video.

Would be awsome if it is possible to connect the N810 to the TV .

I wouldn't bet on it, that it's an AV plug just means that it's the kind of plug that happens to be used for both A and V, thus called an 'AV plug'. It doesn't mean that the N810 has to support _both_ A and V.. (in fact the link you provided says '3.5 mm stereo headphone plug' and specifies the type of plug to be 'Nokia AV Connector')

I agree it would be awesome if it could output video. To be able to connect the NITs to some kind of video display seems to be pretty high on the wishlist for many folks, including myself - I would love to do my pre-made presentations from my N800 instead of having to drag a laptop all the way.

This looks to already have been tried- see the comments by the author at the bottom of this review:

Looks like a no-go, unless somehow this functionality has not yet been enabled through the current OS2008 build.

That is too bad, would be awsome if it would be possible, but maybe it in the future will be possible by Bluetooth I can stream video by Bluetooth from my N81, not the fastest but it works, though my E65 does not since it is v1.2 Bluetooth standard.

Or maybe it somehow can be possible with the USB connection?

Pretty sure not, from some reading around documents at forum nokia in the past.
