Hardware for Analog TV questions
I am building a HTPC (Win 7 Home x64, Gigabyte A75M-D2H mb w/ integrated video, AMD A6-3500 2.1Ghz CPU, 2 Ghz DDR which I will probably upgrade to 4) to use with an analog TV which supports Coax, Composite, S-Video, and Component (YPbPr) video.
I am currently outputting component video via the VGA port and a KWorld PCTV1600 PC to TV Converter (1600 x 1200) with HDTV Support & Remote at TigerDirect.com and the picture is unsatisfactory. The overall quality is acceptable, but periodically, something I would describe as a wrinkle or a wave - that is, a horizontal line above and below which the picture is not aligned - moves from top to bottom on the screen. It does this regardless of the video source, including live and recorded TV (OTA broadcast, thru WMC via a Haupage tuner), Netflix in WMC, and Hulu Desktop.
I saw the same phenomenon when experimenting with the PC to TV device and my primary computer, which is considerably more powerful (3.1 Ghz Intel Core i5, Asus P8P67 mb, 8 Ghz DDR) so I suspect that this is caused by the PC to TV device, but I don't know this. Can anyone help me either troubleshoot my current setup or recommend different hardware to achieve better results? The Gigabyte mb supports DVI & HDMI as well as VGA, so these are options if a different converter is the answer. All input is greatly appreciated.
