I have just got a Pioneer DVR520HS recorder and have a couple of queries.
I am using it with a Thompson TV and all works OK.
Firstly, the manual says that I can control my TV with the Pioneer handset
by inputting a code (62). This is not working. Does anyone know of any
alternative codes?
Second, I want carry on using my existing Thompson VCR which has one screen
menus.
I have connected the VCR to the Pioneer and can only get the VCR menus up
and playback to work with the Pioneer turned off. This obviously means I
cant record on the Pioneer while watching a videotape on the Thompson.
Both machines automatically turn the Tv onto AV1 when connected and I
suspect this is the problem. There does not appear to be any way to alter
the output channel on either the Pioneer or the VCR so that I can set it up
on different TV channel.
All connections are SCART.
Any ideas please
Thanks
Brian
