I've done a lot of research and found conflicting info on some DVD player/TV issues and I am having an ongoing debate with a friend. I am in Canada. I have a 6 year old Hitachi TV, which is NTSC I guess.I have a Philips 642 player I hacked 6 months ago to play PAL and Region 1 DVD's which works fine. My friend thinks if you feed a PAL signal into an NTSC TV it may break the TV (if you insert a PAL DVD). I say the PAL DVD will just not work.She also thinks a N.American TV has to be able to play NTSC and PAL DVD's. I say its the DVD player which determines if PAL or NTSC DVD's will play or not and the TV has nothing to do with it. It can be any make NTSC TV. Am I right?

The DVP 642 converts PAL to NTSC while playing. The TV recieves a standard NTSC signal regardess of the disc type. Actually, you can force the DVP 642 to output a PAL signal or to automatically switch the output to whatever the DVD is. But NTSC Tvs generally will not display PAL signals. Feeding one a PAL signal probably won't break it though.

Based on what I've read on VideoHelp, I think it primarily depends on the capabilities of the DVD player. An NTSC only TV can not properly receive and display a PAL signal, but a DVD player can possibly accept both NTSC or PAL DVDs and output the result as an NTSC signal to the TV, or output both as a PAL signal to a TV, or follow the format of the Source, but the TV must be capable of receiving either signal (I think this is more common in PAL land).

This does not mean the output was changed. As Jagabo explained the output can be NTSC or PAL, but in order for a TV to display it, it must also accept either NTSC or PAL. My understanding is that this is fairly common in PAL land, but it is NOT common in NTSC land. In this case I think your hacked DVD player is outputting NTSC regardless of whether the DVD is NTSC or PAL."Shut up Wesley!" -- Captain Jean-Luc Picard

The DVP 642 converts PAL video to NTSC when you use the patch. The TV is receiving an NTSC signal from the player, not PAL. NTSC TVs do not display PAL signals.

Some hacked dvd players have converters which convert Pal to Ntsc or Ntsc to Pal.This units could output to either Pal or Ntsc television sets.Some are switchable by remote or do it on their own.All lcd set are Ntsc and Pal compatible.Its a little secret not shown on manual specs.I own an Olevia set, no mention of Pal capability on manual, but it is.

The DVP 642 has three settings:
1) Always output NTSC.
2) Always output PAL.
3) Output NTSC or PAL depending on the source. -

Just don't forget that there are TWO issues involved when playing overseas DVD's
1) Region Codes
2) Video Format (NTSC and PAL)
They are not the same. Most DVD Player "hacks" involve region codes.
Simply hacking the region code of a DVD player does not solve the NTSC/PAL problem. -
The MPEG decoder AND the unit's firmware has to already support playing of PAL. It's not something hidden to "hack" (unlock) either. Most "hacks" are not actually hacks, they're simply an unlock of existing options hidden by the manufacturer for whatever reason. A hacker did not actually rewrite code to make the machine work differently.

It seems that no hack is necessary for the unit to convert PAL to NTSC. I'll test in shortly. Does the DVD have to be an authored DVD, or can I load a PAL MPG file and play it?

If I remember correctly (I don't have one anymore) the PAL/NTSC conversion is an option in the standard menus. Be sure it's set to output NTSC. Here it is:

Playing a PAL DVD on an NTSC will not break the TV. The signal will look black and white and constantly roll, but the TV will be OK.
The DVP-642 MUST be set to NTSC output for NTSC TVs. The settings are NTSC (means output ONLY NTSC for ALL video), PAL (means ONLY output PAL for ALL videos) and I believe "MULTI" (means output exactly the same as the source - this is the default value on the 642 and must be changed to NTSC for North American TV users).
Based on my experience, the 642 appears to crop pixels to get the image to NTSC standards. I have no idea if it blends, blurs or drops fields but it definitely seems to crop pixels. It's OK for letterboxed PAL video, but it sucks for fullscreen PAL video. -
Not only does the DVP642 play PAL with no hacks, so do my other two DVD players, one Toshiba, one Lite-On. I guess things improved while I wasn't looking. That's good.

Thanks for all your replies. I wil get to some of them.

I'm having trouble following your logic so let me see if I have this straight.
Before the hack it wouldn't play PAL DVDs.
After the hack it will play PAL DVDs.
This does not mean the output was changed. As Jagabo explained the output can be NTSC or PAL, but in order for a TV to display it, it must also accept either NTSC or PAL. My understanding is that this is fairly common in PAL land, but it is NOT common in NTSC land. In this case I think your hacked DVD player is outputting NTSC regardless of whether the DVD is NTSC or PAL.[/quote]
I am a bit confused here. Do you mean the TV must also accept either NTSC or PAL? Isn't it the
DVD player which gives the signal to the TV to display PAL or NTSC DVD's and that the make of TV doesn't matter as long as its a N.American TV in my case? You say above that after I hacked my DVD player you think its outputting NTSC regardless of whether the DVD is NTSC or PAL. How does that work? I checked the menu on my DVD player and you can choose NTSC, PAL or MULTI. I chose PAL when I first got it and the picture kept rolling. I got it back to NTSC and thats where it is now and I can play NTSC and Pal, but can't play PAL DVD's without hack. -
