Richard- again, it is not the TV set that matters - it is the DVD player that does the conversion. Your TV set is a "RECEIVER" - it will play the standard it is capable of receiving only.   While there are some TV sets with built-in converters, it is more common for the DVD player to have the converter.

I would bet that if you are in Europe, you purchased a DVD player that is multi-standard. An NTSC or PAL will play, provided it is for the proper region.

Also, PC's are neither PAL nor NTSC so it is dependent on the software you use to convert the standard to a signal that will show on your monitor.
