- Do not capture uncompressed! Use HuffYUV (or something newer that does the same trick?) It is a waste of hard drive space to do uncompressed when you have HuffYUV (and other lossless codecs). :)

Agreed. Something newer that does the same trick would be Lagarith (there are others as well, but I've only ever used these two).

- If you are worried about hard drive space you can in a pinch, as said, do two captures and average them, then delete the two sources (keep the average) then do another capture, average that with your previous average, etc. Just remember that with this approach you will need to modify your "weighting" values in your AVS Average script as you go along (.5/.5 on the merging of the first two captures; .66/.34 on the second merging; .75/.25, etc.)

Or, after keeping the 1/2 average, you could capture sources 3 and 4 then average them. After deleting 3 and 4 and keeping the average, you could then average your two files 1/2 and 3/4 with an equal weightng. Needs a little more room, though.

- At least with my set-up, the annoying situation happens of a duplicate frame being inserted by the capture card during longer captures, about one frame every four minutes (to keep sync I assume), the specific result being two frames that look 100% identical, which means one of them needs to be deleted. I search for and remove these duplicates by hand with VirtualDub, but maybe someone here knows an automated way to achieve this?

If you are getting dropped frames when capping LDs, then something is wrong with your setup. In my experience though, dropped frames are unavoidable when capping VHS.

I don't know of an automated way of removing dupe frames, but VirtualDub has a handy keyboard shortcut to jump to the next dropped frame in a file.
