I am a huge fan of 60's and 70's Italian movies, so I am constantly purchasing DVD's from Amazon.it. I probably have at least 200 PAL R2 DVD's. Up until now, my beloved and trusty old Oppo 980H (still working like a champ... and in many ways my all-time preferred DVD spinner due to its swift and precise operation) was the player of choice for such discs, while an Oppo 95 would take care of normal NTSC DVD's and Blu ray discs, SACD's, etc. Some recent Region "B" BD's caught my eye as well, but up until now I was unable to play them. For that reason, I just purchased a region-free, zone-free, modified Oppo 103 to replace the 980H. I have been using it for a few days, and it all seems to work great (love how speedy this unit is compared to the 95).
I'm curious, though. My question for those who do modifications and/or have first-hand experience with modified, region-free players: do these mods affect picture quality/reproduction in ANY shape or form?
