Home Editing of Digital Recorded Tape?

[joe]

hi all,

I want to post videos of my lectures online so my students can access it
whenever they want.

The place I go to makes the video on a 2" (3"?) tape cassette. That is the
"raw" feed and it needs to be imported to the computer and then editted.
Unfortunately the people I am working with are learning as they go so I
spent an entire day making 4 lectures and never getting a single .mov (or
whatever extension it is) from them.

My questions are:
1) can't I do this at home if I get the tape from them?
2) if I can, then what is the equipment I need to purchase in order to get
it done?

thanks in advance for any help you may give me.
