TV refresh rates
I am thinking of getting a new tv. One of the main reasons is my old tv plays NTSC discs in black and white. Its 50Hz and i think to play Region 1 discs in colour you need to have a set capable of 60Hz. But while looking at tvs i noticed most are 50Hz, some are 100Hz. What would be the best advice for getting one? Will NTSC play in colour on a 100Hz tv?

Most 50Hz TV's will accept and display 60Hz. Only a few won't in my experience.
The advantage of 100Hz is mainly the flicker reduction, which for me (I suffer from migraines), it is of vital importance. There are a few "faults" with certain 100Hz televisions (increased smearing etc), but I have none with my Thomson. Above all, if you can afford 100Hz get one, you will most likely not go back to 50Hz due to the decrease in flicker and the increase in clarity and definition of the picture against 50Hz, but if you cannot afford a 100Hz set, then most 50Hz televisions will be fine. Remeber, if you get a 50Hz set that does not display 60Hz correctly, you can return the TV within 21 days by law for a refund. Make sjure you try and find out if they can display 60 pictures first though. I very much doubt any televisions you buy now will have problems. |

louison, you do not need to buy a new TV to watch NTSC DVDs in colour!
Go to your DVD player's display menu and change the display setting to RGB. When you play an NTSC disc you should get colour. It's as simple as that. If that doesn't work, make sure your DVD player's SCART lead is connected to AV1 on the TV. On most TVs only AV1 SCART does RGB. |

I'm not sure that all dvd players will output 50Hz from an NTSC source. Some put out PAL60 which is 60Hz (strangely enough). Try and see if it works.

The reason most DVD players output PAL60 is because it's not only easier/cheaper to do (it just a matter of sending the relevant parts of the picture information in the right way), but players that change to PAL50 do so by dropping frames from the picture (from 30 frames per second down to 25, a loss of 5 frames every second of picture). In most cases this will produce a jittering of the image which is most noticeable when the picture pans or there is movement across the screen. Some people find this very disturbing and therefore if you can watch in NTSC or PAL60 you will be better off.

I should have mentioned that my dvd player is my PS2. I have a Region Free disc but it still plays them in Black and White. There doesnt seem to be anything i can do to change this so it may be Sony not wanting its customers buying cheaper games elsewhere.

That where your problem is. The PS2 will only output NTSC (region 1) disc in NTSC format. Therefore the reason your TV is showing them in black and white is because it is not compatible with NTSC signals.However if the picture is stable (even if it's black and white) then the TV should be capable of showing PAL60, so buying a cheap multiregion DVD player should enable you to watch region 1 discs. |

I used to use my PS2 as a DVD player. I had a region 0 (NTSC) dvd from the states. It worked o.k. on a Panasonic TX28PL10 (100hz) TV. It played in colour without any problems, through S-video. However I returned the TV because I did not like the smearing effects assoiciated with 100hz with this particular model.
I then tried a 100HZ 28in Sony TV. My NTSC region 0 DVD would only play in black and white on this TV. It is not your PS2 it is the TV that is at fault. I returned this TV aswell and now have the Panasonic TX32PL1 (50hz), no noticeable flicker, better picture and it plays my NTSC DVD's and games in colour. Yes even PS2 games with 60hz modes would not play on that Sony 100hz TV. To repeat it is the TV that is as fault not the DVD player. |

I wouldn't describe NTSC discs playing in black and white as a fault of the TV, but rather a missing feature. Using RGB or S-VIDEO sends the colour to the TV uncompressed which gets round the problem of the TV not supporting NTSC colour decoding.
I don't have a PS2 to hand but I do know you can select RGB in the BIOS menu. Surely that should solve the problem? |

No because the cable used to connect the PS2 to the TV is a crappy Yellow/White/Red Composite cable, not a fully wired scart lead, which is required for RGB.
This will do the trick. http://www.argos.co.uk/webapp/wcs/st...clickfrom=name |

The terms 'PAL' and 'NTSC' are misleading when it comes to DVDs because they are terms for the colour encoding of analogue television, NOT anything else. They are, however, assumed to mean 50 and 60 Hz.
We, for example, on analogue, use PAL-I. It's the 'I' which denotes a 50 Hz, 625-line display, as well as a few other things. PAL-M, used in parts of South America, denotes a 60 Hz, 525-line display. Not a mention of NTSC there, yet I mentioned 60 Hz. |

No. It's just a letter.
