3:2 pulldown has to do with cinema 24fps that has been "upsampled" to NTSC 
which may cause artifacts when digitized and that's why there are 3:2 
pulldown filters AFAIK. It has nothing to do with the "panning and fast 
movement" artifacts that occur with bktr and cxm video decoders, especially 
when scaled down to sizes divisable by 16. As I understand it, this is the 
result of a poor comb filter. Ffmpeg's deinterlace function eliminates this 
problem completely on my PVR-150 (using kbtv2's backend which is almost the 
same as ffplay).

Note it says PAL-I too, so your PAL-I should be supported alright I reckon.

It's clearly not a tuner problem but a problem with the video decoder. The 150 
and 500 have another type of video decoder chip than the 250/350, so I can't 
really say much more about it.

HTH,
