Picture Mode has to do with how the 876 de-interlaces interlaced sources... the optimum de-interlacing algorithm is different depending on whether the interlaced source is film-based (24fps) or video based (30fps). It has NOTHING to do with converting frame rates from 24fps to 30/60fps, or vice versa... and it has nothing to do with playback of progressive scan (non-interlaced) sources, regardless of frame rate.
Your TV also has a similar setting, and it works the same way... optimizing the deinterlacing process for interlaced sources only. Again, it has nothing to do with converting frame rates.
Essentially, the only common source of interlaced 24fps video is an SD DVD player that is configured to output 480i/24 (or 1080i/24 - which I do not believe would ever be a wise choice if you have an 876). If you feed this into your 876 with the output upscaled to 1080p, then the Film Mode setting could come into play. However, 99.999% of the time, leaving it set to Auto is just fine because it will then auto-detect that it is a 24fps source and choose the correct de-interlacing process. In this case, the setting in the TV would have no effect whatsoever because the source, as the TV sees it, is already progressive scan. If you were to feed the 480i/24 DVD source directly into the TV, then the setting in the TV might matter, but again the Auto setting should work correctly 99.999% of the time.
The only device in most HT systems that can do frame rate conversions are typically DVD and BD players, and they typically can only convert 24fps sources to 30/60fps (using the 3:2 pulldown scheme) to prevent downstream devices that cannot handle 24fps sources from ever seeing them. No common device converts 60fps video to 24fps.
Now, to your A650 TV... as a native 120Hz refresh display, all common frame rates are even submultiples of its native refresh rate. It can display both 24 and 60 Hz video without resorting to any reverse pulldown shenanigans... 24Hz sources will repeat every single frame 5x (straight 5:5 pulldown) to fill the 120Hz display refresh rate, and 60Hz sources will repeat frames 2x. There is no need, as in a 60Hz display, to resort to 3:2 pulldown to make 24Hz video "fit" into a 60Hz refresh rate.
BTW... if you feed a 1080p/24 signal from a BD player through the 876, regardless of what your Monitor Out or Source Setup settings are, the 876 essentially goes into a true "through mode" and virtually no video processor functions remain functional.
Sorry if that was TMI, lol.
