I have only had a PTAE100 for a couple of weeks now and find it excellent. I have a 80" screen. I have been using a EBench KH777 player as the source. This has progressive scan and looks wonderful. However, it is very tempermental and can fail on some DVD's. I have a Sony NS900 that plays everything but doesn't have PS scan. I put a cable on the Sony to compare and the picture looks a bit blurry. Subtitles are not sharp. I put the same cable on the EBench and it looks fine. Subs are sharp again. The strange thing is I tried the Sony earlier with a temporary screen and it looked fine. The screen was much closer though. I have read what PS scan is, is this a difference between interlaced and PS scan?
