Ok here's some screenshots:

First off, I think the PCTV card is unusable to me unless somebody can tell me how to get rid of the constant dropped lines? I think the theater 750hd chipset is several notches above the pinnacle chipsets when it comes to y/c separation and rainbowing. If you look at the finer details of the japanese subtitles it's very apparent imo. The usb stick is almost as good as the pinnacle pci card when it comes to rainbowing. This surprised me as the stick has a 1 line notch comb filter and the pinnacle pci has a saa7134 chipset with a 4 line adaptive comb filter. I haven't noticed any of the problems with agc on the theater 750 like people have been talking about in the forums online. I'll admit I'm a total noob and maybe my eyes aren't trained to catch it. As of now though it seems clear to me that the Theater 750HD is the way to go but I am posting these because I want feedback and suggestions so please feel free to tell me what you think.

EDIT: Viewing the images at full resolution reveals a lot more than these resized images btw.
