You're right with most you wrote. But it's actually quite easy to get decent quality VHS digital captures. Most of the problems of VHS are caused by the inferior standard and aging. Resolution is less of a problem. VHS is just enough for a tube TV set to be displayed right, but digital equipment is far less tolerant with signal deviations. But there are devices that can take care of most of these problems. They digitize each video frame line by line, manipulate it and output it again. They throw away the color subcarrier burst and the sync signals and generate them new. Furthermore, they start each video line at the right time, so you get clean edges. Better devices let you boost or lower black level, luminance and color, throw away one video field (half-picture), slightly move and resize the picture and be perfectly in line with the studio sync. They're called time base correctors or frame store synchronizers. They're difficult to handle in live environments as they delay the video signal one or multiple frames, so at least the audio must be equally delayed. But you'll get real good results, even at home. Better later S-VHS machines had simple TBCs built-in, so you might go for one of these you can get cheap and redo the stuff that didn't look too well. These also handle the audio delay internally.
