Not when trying to distinguish between the QT X and the classic QT 7 player apps and their playback capabilities under Mavericks.
Sorry, I did not want to be pedantic. QT X (64 bit) aka AV Foundation, classic QT 7 (32 bit) aka QuickTime, okay. But it seems that people are confused: they think that QT X has something to do with QuickTime, and they request updates because they think QT X has something to do with QuickTime.

Obviously you did not bother to download and play the linked file provided in my post and try playing it in the QT X...
Sorry again, you are correct: I did not even try. I did it know and learned that there is one ⚠ more compatible video format.

However, this is not what really concerns me sinc I do not normally use the QT X player under any Mac OS X version.
Same for me. But I guess that Apple will remove 32 bit support in (near?) future. And then it will be a problem.

Might have been more informative had you actually posted the specific audio and video formats here so I could add them to my list of "problematice" AVI codecs...
I did not because the list of incompatible video formats is longer than the compatible video formats. And it is not helpful for me if AV Foundation recognizes the AVI container, but can not play its video format without conversion.
Compatible (as far as I know / tested): H.264, MPEG 1, MPEG 2, MPEG 4. And "your"
Motion JPEG OpenDML. MPEG 2 can be opened by QT X without conversion but is not really playable here - it stutteres very much.
Incompatible (as far as I know / tested): DivX 3, DivX 4, DivX 5, Indio 3, MS-MPEG 4, PIM1, Sorenson Video, Sorenson Video 3, Sorenson H.263, TrueMotion VP6, WMV 7, WMV 8, WMV 9, XVid. And "may be" the codecs you mentioned (AIC, Animation, PNG, some specific ProRes 422 family codecs, DV stream files). Obviously there a many more formats / codecs...
Even worse: the converted videos are bigger (1/3 to triple). And some of the videos stop convertion after some minutes.
