I use good old reliable WinDV for capturing video from VHS. I also use a camcorder with pass-thru.
It's free, easy to use, and you can set the size of chunks of video that it splits it into.
I don't use Liquid, but back in my Studio 9 days I would occasionally run into an OOS problem. I found that by capturing in 10 or 15 minutes chunks of video the OOS problem went away.
