Rather than go the hard wired route, I opted a while back to wirelessly distribute Sky from the main MySky / AV Theatre system to secondary TVs around the house.

I bought a $250 DSE 5.8Ghz unit over a year ago and it seemed to work well enough so bought another in April this year. Each unit was set on a different channel. All worked well.

Then a month or so ago, the first sender unit packed up for no apparent reason although the IR extender had been flashing spasmodically and without "instruction". DSE tested it and found "no fault"; there was a row about the $50 service charge, but irrespective of that, the unit didn't work at all when put back into the system so I ditched it and have run both receivers off the single sender on a common channel. All worked well.

Then a few days ago, the second sender unit packed up, again without apparent cause. I could take it back to DSE, but history will no doubt repeat itself and DSE will again try an stick me with a $50 service charge for a "no fault" outcome - when it clearly doesn't work anymore.

I'd rather not go there, put the whole DSE thing (and $500) behind me and not buy from DSE again, but that pre-supposes I can source reliable / professional 5.8Ghz AV sender / receiver equipment to replace it.

Does anyone have thoughts and ideas on:

1. How reliable these Chinese manufactured / proprietary badged 5.8Ghz units are in practice?

2. Why are the 5.8Ghz units considerably more expensive than 2.4Ghz units? The latter is no good for me - I've tried it and it simply crashes the house wifi dead, irrespective of channels etc.

3. An NZ source of reliable / progessional 5.8Ghz AV sender / receiver equipment?

4. Should I just give up and go wired or get a second / third Sky decoder in order to get reliability?
