Does the player that you use for the television do progressive scan? __________________________________

I'm not sure to be honest but I think it's interlaced. It's a 42" Samsung plasma about 6 years old. Could that cause it? Can I change the project to interlaced?
Thanks for your help, I'm new to this but finding it very interesting.

Sorry just reread your post. The player is a Sony home theater, DAV-SA30. It must be 10 years old. Looking at the manual it does interlaced and progressive.

Edit yet again. Having read the players manual it says - “PROGRESSIVE” does not work for PAL signals.
Even if you set “COMPONENT OUT” to
“PROGRESSIVE”, the output signal is automatically
switched to interlace format for PAL signals - Is this my problem?

I would say that is probably the problem. The DVD produced by PD is interlaced. Some players will convert to progressive, but sounds like yours does not. You are likely to only notice the difference in motion scenes like you described. __________________________________

Thanks Jaime-esque, It makes sense, if I play the disc on my sister in laws much newer player, there is no problem. My Sony is about 10 years old. Today I have ordered a Panasonic SC-BTT500EBS. That should sort me out. Thanks again.
