Hi all, I have just started receiving our local ABC station (WJLA in Washington DC), however the picture sucks bigtime, halos around everything. I was previously under the impression that Toshiba sets would upconvert a 720p signal to 1080i for proper display, but now I am beginning to wonder. I use Echostar's HD6000 as both DSS and OTA receiver. Will I need a separate receiver to do upconversion prior to reaching the TV? I'm thinking its about time I looked into a home theater PC. Thanks in advance for any and all thoughts.
