off topic: video processing for quality picture reasons from SD source.

Hi anyone, I have been researching and trying some softwaresolutions and hardware with poor success and output to a 1080 LCD TV (high end) thus bypassing the TV's scaler and display direct without processing. Canada still do SD stuff till Aug 12 20011 HDTV switch over. flat panel TVs with built in tuner do rather hack job of SD video that I knew these should do good job. Ditto with composite and s-video. But there is bit of unique issues that will be addressed below. I have tried three video capture cards and software solutions, constant fussing and long start up, average picture quality, tend to be darker. And second issue is EIA608 is closed caption (CC) decoding for SD and displaying does not exist or erratic working in many software and hardware. I already tried a JVC HM-DT100U and it has tuner and output on component or HDMI but internal video processing for SD is not up to standard and as bad as youtube quality with heavy artifacts. Video processors, DVDO Edge does not have CC capability. I sent email to Anchor Bay Tech of their product and they do not implement this at all. If it was, that would be end of the story and bought the 800 buck video processor. But I'm still not sure of their quality. So I still exploring options and thinking of solutions. I intend to use a old S-VHS VCR as tuner and output on S-video. I have not found a decent a device that has high quality processing and output on HDMI or all analog circuitry and output on component to take advantage of higher quality A/D coverters found in TVs than composite or s-video. Options: 1. Buy DVDO Edge and s-video CC decoder. But I'm not sure on DVDO Edge's performance. 2. Buy up broadcaster quality equipment: Obtain RF demodulator (channel selectable via keypad or remote control of some type (remote or PC) with SDI output box (some can deal with CC onboard which is nice), or same idea except output on component if there's one. If it is SDI output and no CC, buy SDI CC decoder with CC overlay box, and get Blackmagic Design's "Monitoring HDLink Pro DVI" to hook all up. I have found one or two on some of these but cost for new one is way over 2,000 to 5,000. Ouch. Used source is best option but where to go? I tried broadcasting engineering forum and smartcow both does not address what I'm trying to find and get suggestions. Another reason I really like broadcaster equipment concept is these have deep bandwidth and little processing (selectively is good) and easily plugs together, setup and forget it, just punch in channels. I'm that fussy. CRT on SD quality is excellent and I use cable, built in video processors in TV threw away too much, soften and lose details to brother me so much enough to get me in a tizzy. I know broadcaster digitize all in and out feeds but quality is much higher. Cheers, Wizard
