Did this ever get solved?
Whell, were still trying to solve it.. as you can see there have been many posts by me and ozzman lately.
And if you have the same TVcard then maybe you can join in, and try a few thing out i mentioned earlier in this thread.
If its a different card then these steps would have to
-look in logfiles if there are any easy messages that indicate what is wrong.
-search the forum for any error code's that appear in the logs.
-update all drivers and try the newest SVN versions of MP / TVE3
-change the devid in capturecard definitions. like in post : #14
-Try to connect to a graph in graphedit (if you have a other working TVprogram while watching live TV)
-Try to create a working graph manually in graphedit
Also post lots of info about what card your trying to use and what you have tryed so far..
If its a different card then the "PINNACLE PCTV PRO 110i" then start another thread and post the info there..
(you may also post a link here to that thread then if you want
