I've seen the Philips DVP-642 and it has poor PAL->NTSC scaling. It probably used a nearest neighbor filter (just dropped scanlines) to resize from 576 to 480 lines. Frame rate conversion was smooth, probably 3:2:3:2:2 pulldown.

I have a DVP-5960 and it has both good scaling and good frame rate conversion.

I haven't seen the DVP-5140. I suspect it's the same as the DVP-642.

My old Liteon LVD-2002 has good scaling but mediocre frame rate conversion. It simply repeats frames to go from 25 to 29.97 fps.

This is all with progressive PAL DVDs played back on an SD NTSC CRT TV via component or s-video. I don't have any interlaced PAL DVDs to test.
Well I had a Philips DVP-642 for a short while (it lasted all of a month or so before breaking down on me) and it had the worst PAL to NTSC I've seen since the early days when Apex and Sampo where the only option but either crushed the image or stretched the image (based on if it was a 4:3 DVD or 16x9 DVD).

The Philips DVP-5140 is much much much better but is still a far cry from my Cyberhome CH-DVD 500 which is not perfect but does a damn fine job of PAL DVD to NTSC in terms of resize and frame rate conversion. Of course the Cyberhome CH-DVD 500 has other image issues (a slight red "push" and issues when in 480p progressive scan mode).

My guess is the Philips DVP-5140 and DVP-5960 have the same image quality when it comes to PAL DVD to NTSC. After all they use practically the same MediaTek chipset.
