   Older VHS video recorders can handle 405 line material with few problems.   
   The Ferguson Videostars or their JVC equivalents are good choices. Around   
   1988 there were changes in circuitry that prevent them from properly   
   recording and playing back of 405 line material. Possibly something to do   
   with Macrovision.

   I am sure that there was a VHS video recorder from the late 1970s that   
   could be used to record both 405 and 625 line broadcasts and playback to   
   both 405 and 625 line TVs.
