bob, I found your long explanation very helpful and interesting. However, my question is concerning what happens with 576/50 PAL SD-DVD (region 2) disks?
Please correct me if I am wrong, but my limited understanding is that when playing a 576/50 PAL SD-DVD at 24p the player assembles every two input frames into a single output frame, and spools that to the Tv at 24Hz, so the movie duration becomes 50 / 2 / 24 =104% of the original scheduled length. Is that correct?
In other words, if (as in my case) your DVD library consists to 99.9% of 576/50 PAL material, then presumambly it is perfectly Ok to leave 24p conversion set to "On" all of the time. Or?
And, (second question), what happens to the audio sync in this case? I could imagine that if the player is spooling the video at 96% of the scheduled rate, but the audio is spooling at 100% of the defined PCM rate, then one would start to get lipsync problems. In which case, that would get worse the longer the movie has been playing. Or does the player add audio frames to pad out the sound track to keep it in sync with the video? In which case, then the audio quality is being compromised.
