First time post for me. I am having issues with HD200 satellite receiver outputting on DVI cable. Equipment being used is a Samsung HLM507W 50" rear projection DLP television and the Sony SAT-HD200. According to the Sony manual on page 11 (from memory) the available output formats from DVI are: 1080i, 720p, 480p, variable 1, variable 2, variable 3, Auto DVI. When connected to the Samsung, the only outputs that I can scroll through (using the format button on the front of the Sony) are 720p, 480p, 480i (no picture) and Auto DVI (which puts out 720p). I cannot get the Sony to output 1080i for any reason. I know that this is not so much of an issue with a native 720p display but I would like to know what scales 1080i material to the displays native resolution better - the set top box or the television. When I talk to Samsung, they tell me that their T.V. will accept 1080i, 720p, 480p on the DVI input. Sony tells me either that they don't know or one person told me that it was the television talking back to the HD200 and not letting it put out 1080i - ? This is also the same guy who told me that DVI is not better picture quality but only for HDCP copy protection (I don't personally believe this, or else my eyes are wrong and every HT publication is lying to us about the benefits of pure digital paths). Does DVI transmit data both ways? It does not seem correct to me that I can't send 1080i material all the way through to the television and let it's scaler do the conversion. Has anyone else had this problem or has anyone else been able to send out 1080i from DVI? By the way, I can get it to send out 1080i on both the component video and VGA outputs. Thanks.
