KV-34XBR910 vs. KD-34xs955

Are there any more somewhat significant differences between the two besides:

KV-34XBR910
- Picture-and-Picture
- DVI input

KD-34xs955
- Independent Input Memory
- built-in ATSC and QAM tuners
- Can sort of control aspect ratio of HD sources (just a Zoom option?)
- Memory Stick reader supports a few more formats
- CableCARD slot
- HDMI input

Also, I heard that the XBR960 and xs955's Super Fine Pitch tubes are apparently more vivid than the 910's (read something about 910 being more dim)---is this true? Would ISF calibration be able to close the gap a bit between the 955 and 910?

Regarding the Independent memory input: since the 910 doesn't have it, does that mean after an ISF calibration meant for movies and television is complete, the PQ for video games would not be as good as it would be if a specific input dedicated for gaming was calibrated for such on the xs955? Is it a pretty significant difference in your opinion?

Finally, does the SFP make 480p sources look any more detailed than say 480p on an XBR970, even if just a very small increase?

I asked about the picture mode thing in the Display Calibration section, but it sounded like the majority of HDTVs don't have the ability to be calibrated that way.

Or maybe they just can't be customized as well as an independent input memory can be, but still can be adjusted enough for a decent change for games.

Checked them out, and it looks promising


My bad, I thought the 955 didn't have the built-in subwoofer.
