I am using a Pinnacle Studio DC 10 Plus on Windows XP.
Problem is I can capture but when I click the stop button in Vidcap it crashes leaving an avi file but with no header information which Vegas cannot find, saying it cannot determine the stream.
A very few people have claimed they are able to use the DC-10 under some configurations, but we have seen many problems with this card and do not recommend or support it- sorry.
