What? You are really kidding right? In short,,, it will look like total crap!!!
Maybe 2 hours per disc for top quality or maybe 4 hours for mediocre quality but trying to fit 8+ hours is totally unrealistically. Considering that you transfered from Cam to VHS and now want to do VHS to DVD. The old second generation problem crops up. You should have gone from CAM directly to the DVD in your recorder. I hope I interpreted your post correctly.
