hmmm.....if you get dropped frames that would indicate a problem with the PC and not the 'pass-thru' solution. I would assume you defrag your capture drive periodically and that you use a separate drive for capture....there are certain optimization tips you can apply to improve your capture. I've posted a link on the forum about that. Also, try to capture your footage to a DV tape and see if you get any dropped frames. Then capture the DV tape to your PC and check again for dropped frames....if you still get them it means it's your PC.
