hi ryanenen hing, the problem is that my dad's old plasma gets only S-Video and VGA inputs. so that the only way i can think of for a better image is to make use of 倍線器. i am now connecting a STB to the plasma with S-Video but the effect is really not good ar. i have no $$ to upgrade the TV and making use of 倍線器 should be the cheapest solution for an "upgrade".......
-> Simon hing, thanks for the info. will try to look around in 鴨記.
-> ryanenen hing, have a glance on the PE1000, a very good product and it fits 100% my need. cannot find it in HK 2nd hand market. will keep an close eye here....
