Hopefully I can help even though I have to confess that I don't use movie edit pro.
The detailed manual is a pdf link and can be found on the magix site.
As for analogue capture, i'm not sure how you have it connected to the PC but normally the signal will need to be converted from analogue to Digital. In my case I use a TV tuner USB dongle and I connect my VHS to that, then capture using my video editor. It works fine for me but without the TV card I wouldn't be able to capture anything.
advice well meant, but I don't think that you will find a link to a pdf file on the website, 'cos I didn't. However, contact Magix directly and they'll send you what they've got available.
