Hi all, we have we have a standard Sky box.  Primarily b/c we get Asian channels via WTV and they don't provide HD.  Had this for about 10yrs.  It has RF2 output or S Video and LR Audio.  Would it be fair to say the two are similar quality that RF might be preferred given its simpler one wire setup?

We prefer to link it from the Sky box b/c at times the TV might be off.  The setup is basically TV room to upstairs (3) and downstairs (1).  So a 2 way splitter at TV and then a 3 way splitter upstairs.  The Sky box does have a VCR SCART outlet.  Not sure if that helps.

I did some goggling and on Youtube I found out one method you use 2x Cat5/6 cable to extend HDMI.  Interesting but we don't have MySky HD and our TV is still CRT, don't laugh as it's still working, LOL, but the Sky channels we get are not HD anyway. 

So basically - is it RF2 or else upgrading and go HDMI?
A little side question - the Sky dish we have now and the VHF aerial the cables don't have exterior housing - that's fine right?  They were both installed by contractors. 

I thought about television b/c I am about to do some Cat5/6 cables around the house hacking my way through as I am not breaking walls down. 


Many thanks.

Edit - can you run Cat5/6 cable and use it for RF or S video and LR audio?  That way in future I could change the wall plates to HDMI.  Reminds me I don't have TV with S Video - d'oh only from the Sky box.
