Playstation 3 Blu-ray playback of scratched discs, 1:1 aspect ratio?

[creakndale]

I currently have a HTPC which is used to record HD OTA and play DVD's. I also have an older Sony non-upconverting set top DVD player. My projector is a Sharp 720P model with a DVI and component input connections. I rent a lot of DVD's and unfortunately most are scratched to different degrees.

The HTPC is connected via DVI and has a suberb image quality (running TheaterTek) with an exact 1:1 perfect aspect ratio but if I play a badly scratched rental disc the HTPC's DVD drive hits the bad spot and will spin forever, never moving beyond the scratch.

The Sony set top DVD overscan player connected via component cables will hiccup at the same scratched disc area but it will continue to try to get past the scratch eventually skipping forward.

So my questions are:
1. Does the Blu-Ray drive in a Playstation 3 try to "get around" a scratched disc or will it just lock up when it hits a bad spot?

2. Does the Playstation 3, in 720P mode, output a pixel perfect 1:1 non-overscanned image like my HTPC?

Thanks,

Overscan is a property of the TV, not the player. Players send the entire video frame to the TV. The TV decides whether to overscan or not.

One exception is the video output from some graphics cards that try to compensate for television's overscan by downsizing the actual video frame and padding it with borders so that the borders get hidden by the TV's overscan. But since TVs vary in the amount of overscan this is never perfect.

I suspect your computer might eventually get past the bad spots on the discs. But computers are designed for reliablity of transfer not realtime video playback. They will retry over and over again in an attempt to get the data without errors. The retries may take several minutes per sector. So it may seem the video playback has locked up.
