When a VHS, DVD or laserdisc is released using the NTSC format it can have a maximum resolution up to 525 lines with a vertical frequency of 60hz. The answer is no. TVs are either NTSC capable, PAL capable or both. Unfortunately, nearly every TV in the United States is NTSC only. If you live in a country where PAL is the standard you can generally get a TV that is capable of both PAL and NTSC native playback.
Lets look at the possible solutions and the good and bad of each.
Native playback of both signals. Power converter needed. High quality conversion if you get a nice model. Quality isn't as good as the other solutions, often producing MPEG artifacts on playback. Also keep in mind that your VCR or laserdisc player has to be capable of NTSC AND PAL playback.
