As most of us know They might on the wrong side of the pond, but then over there they have to put warnings on the top of champagne bottles not to point it at your eye when opening and stamp the base with "open other end". Panasonic kit sold in Europe will allow any amount of manual DTV tuning to add individual channels if you have the patience to do it. Autoscan tends to be more convenient when new channels pop (briefly) into existence. The most annoying thing is that several designs reset the favourites lists whenever you make a change using autoscan. > DTV is unreliable, meaning sometimes channel 6-1 pixelates out, > sometimes 58-2 is gone.

If your terrestrial DTV reception is so dire why don't you use Freesat or whatever it is called over there to get the free to air channels? Regards, Martin Brown

Douwe Egberts , well, I am into drinking thee lately. >>>>>> And also the source material counts, garbage in garbage out. >>>>>> >>>>> Dancing with the Stars from BBC is super material, you really >>>>> see a difference. OK a quick google solved the mystery: http://news.bbc.co.uk/2/hi/entertainment/4709410.stm So it is US made, but a BBC copycat. Maybe BBC is mentioned as they probably have the copyright to the show type. Then it will be recorded in US format. >This is what's cooking these days: > >http://www.ikegami.com/br/products/hdtv/pdf/HDK77EX0401s.pdf Ikegami, I have worked with those cameras (not this one), was responsible for that in some big productions, been all over Europe with Ikegami:-) The old ones in my times still used plumbicons...

We >rather spend that money at the Japanese restaurant, like today :-) Na ja, DVDs go for a few cents these days, Blu-ray is still relatively expensive. Need storage space too, huge harddisks are cool as long as you do not drop them. But if you buy a movie, and it is HD on Blu-ray, then you need a player at least.

So the drill is to wait for a weather pattern that will show most DTV signals, peek outside and listen to the scannner to make sure no Fedex freight aircraft is on the approach, hit auto-scan and hope that as many DTV channels as possible stick. Then delete the flakey ones. >> DTV is unreliable, meaning sometimes channel 6-1 pixelates out, >> sometimes 58-2 is gone.
