OK, it seems like I have a problem recording in the HS speed.

Only seems to be a record problem, as I can play back older HS speed HDTV recordings just fine.

I can also record at all other speeds, just not in HD of course. When these machines sense an HD signal, they auto-switch to the HS record speed.

Question: Does anyone know which is the HS record head, so I can clean it.
I don't have a service manual, so I have no way to know which of the many heads is the one to clean.

is it labeled somehow - it must be, yeah?

Service manual is available here: http://www.digitalfaq.com/forum/vcr-repair/4769-service-manual-jvc.html

It might be worth asking for repair advice while you are there too.
