Canopus ADVC-100 VHS to Digital Converter

I bought a Canopus ADVC-100 a long time ago and never got around to trying it. I need to convert all our old VHS tapes before they completely rot. It has been a session getting it to work.

The big thing for me seemed to be the fire wire connection.
I added a fire wire card to an older Windows 10 desktop with no success.
I tried a Win10 laptop with an internal fire wire connection with no success.
I tried a Win7 laptop of the samp model and bingo . . . it worked
  (Note - The manual said to have the fire wire connected and then boot the PC. This worked - I did not do that with Win10 so need to try it) (Maybe this was the missing step for my previous tries.)

The S-Video connection didn't work on anything. Only the RCA connections worked.

The Win7 software that worked so far is:
1. WinDV 1.2.3
  * Sound is recorded put not played back during process
  * Starting capture before starting the player works
  * The AVI packages contain an uncommon codes as far a I can tell but works fine.
  * quality from a good source is surprisingly good.
  * I need to try VirtualDub to join the AVI packages
(VitrualDub2 handles mp4) - If one file does not open, try another and then try the original.
  * Avidemux works also.
  *Then try Handbreak to make MKV files.

It was working great. Then it would capture the video but not save the file. Irritating . . .
It started working again. Mysterious . . .

A work in process . . .

To Try
Enosoft DV Processor

This seems to be the scoop:
1. Be sure the Canopus is set to "analog"
2. Start WinDV and be sure it sees the video player
3. Click the WinDV's capture button.
(You should see everything that is happening on the VCR on the WinDV screen)
4. Hit play on the VCR
5. How files are saved. WinDV seems to detect when the scenes change. Not sure how. But It will save clips based on something other than a preset time. If it quits saving, restarting Canopus and WinDV seems to restore saving ability.

Try this when stitching together . . .
VirtualDub:
File -> Open AVI File
File -> Append AVI Segment (automatically appends sequentially numbered files)
Video -> Direct Stream Copy
File -> Save as AVI
