I'm not acquainted with your precise camcorder model so I can't give you specifics, but these are the pass-through basics.
1) Remember that there is no connection between the camcorder you're capturing from and your computer, so you can not use the playback controls to start and stop your analog camcorder. You need to operate this camcorder manually, using its controls to play the video.
2) The pass-through camcorder must not have a tape in it.
3) Watch the video from your analog camcoder and, when you are ready to capture, click capture. As I said, you will not be able to control the analog camcorder from the program.
4) This is a hybrid method of capture, so the program can get confused if it starts looking for timecode and can't find it. Do avoid this, go to the >> menu and open the Device Settings. Make sure that all options related to droppped frames are unchecked -- particularly the option to stop capture if dropped frames are detected. Also, in the capture panel, you must ensure you do not have the Break by Timecode option selected.
That did the trick (changing to No Drop Frames option). Thanks for saving me again!
Glad to help, Scout!
