Sanyo Betamax Front-Loader VTC-M range and VTC-NX range: Idler and Belt Replacement (VTC-M20 shown)

This Sanyo VTC-M20 needed new belts and idlers, so I decided to document the replacement process. I'm no expert, so there may well be better ways of doing this - feel free to comment! All of the Sanyo VTC-M range use the same mechanism, as do most of the VTC-NX range (I believe the VTC-NX100 is the exception). 00:00 - Intro, and Disassembly 02:14 - Identifying the Belt Locations 02:51 - Replacing the Loading Ring Belt 06:03 - Removing the Idler Assembly 08:01 - Replacing the Idler Tyres 10:27 - Reinstalling the Idler Assembly 13:07 - Explaining how to access the Cassette Loading belt 15:14 - Replacing the Cassette Loading belt 18:32 - First test of mechanism after fitting new parts 19:40 - Playback test - will it work?
