Hi guys, I have signed up with local cable provider here and got an HD set top box. It is the Scientific Atlanta 3250 HD. I think I got it figured out but want to confirm a few things. First off my TV is the 34HFX84 from Toshiba and as it does 1080i or 540p I have set output to 1080i on the box. Is that best? options seem to be to chose an output (from everything from 480i or 480p to 1080i) or set to auto or something like that. I assume one option has the set top upconvert it all to 1080i and the other send the signal as is to the TV and IT does the upconverting. Should I assume the TV will do a better job? Second is audio. under settings for Audio the is one called Digital out. the options are Dolby Digital or Other. I had it set to DD and I was occasionally getting audio drop outs. When I called tech support the tech made me change the setting to other. Well now all channels give me pro logic rather than 5.1 Now my amp is the Pioneer 814 so it tetlls if the signal is Dolby Digital but does not specify 5.1 or 5.0 etc... So with the setting to Dolby Digital my amp tells me all HD channels have Dolby Digital (theoretically 5.1) and all other channels Dolby Pro-Logic. which is best? are the channels 5.1? or is it upconverting?
