I can't answer your questions; however, I can tell you this:
All the Sony televisions sold in the US are hardwired for NTSC. If you bought your Sony TV in the US, it will not display pictures from a PAL source. You will need to convert PAL to NTSC.
Some DVD players can do internal PAL-NTSC conversion. I don't know about Laserdisc players. There are outboard PAL-NTSC converters on the market.
