Is there anyway i can hook up my camcorder to my pc so that i can have a Powerpoint presentation on the screen with the actually stuff that im recording in front of the presentation. Like the shopping channels have.

Best way is to export your edited footage as a .wmv or .mov file then import that into your .ppt doc.

For this to run well you would probably have to copy your presentation onto a hard drive rather than straight from a cd.
