Jvc Pd-42b50bu

[Grahamc]

My daughter and son in law have bought us a ( secondhand ) JVC PD-42B50BU plasma telly. I have been reading up on them as it has no owners manual ( managed to find and download a pdf one ) I know it does not have HDTV but it does however accept a watered down form of hd via one of the input sockets ( may be the S-vid I cannot remember which site it was that I read it on ). Is it worth setting up this watered down version as I have a Pace DS810 or is it not worth the effort for what little change it makes.

I also read that it can be set up for surround sound ( I already have the set up on the old telly ) but there are only the sockets for a centre speaker and left and right speakers, would it work if I connected the back left to the left speaker and the same on the right ? or is their another way ?

Can anyone explain the "Decoder function" in any sort of detail

Thanks to anyone who can help ( and if you do, get ready for more questions )

Regards
Graham
