Page 1 of DVD`s in NTSC won`t play as smooth as in PAL because of the difference in FPS

When I play a dvd that has 24 or 25 FPS (PAL) then the picture is smooth. When I play another that has 29 FPS (NTSC) the the picture is a bit slow now and then.

Is it the DVD`s fault or my TV`s???

It doesn`t bother me, but I would like to know what could be done to fix this happening.

Note: FPS = Frames Per Second, for those who doesn`t know.

TV: Sony KV-25C1E
DVD: LG RC-68223

Here`s full info about the dvd player (description in swedish and technical info in english):

This may be a result of NTSC-PAL conversion:

You can resolve the problem by turning off the PAL60 Conversion feature on your DVD player. (I could be wrong!)

After 3:2 pulldown NTSC runs the same as film,that is 24FPS.
The juddering is because your dvd player is outputting the NTSC as ,most likely PAL 50,but possibly PAL 60.
Go into the setup menu on your player and change the video output to AUTO.This should allow it to output NTSC in pure form.If you have picture problems on that setting then your tv won`t accept pure NTSC and you will have to tolerate the juddering

PAL60 shouldn`t judder as it uses NTSC`s refresh rate and PAL`s colour timing. It sounds like it`s either being converted to PAL50, which can cause juddering, or you`re just noticing the 2/3 pulldown artefacts. You can lessen these with a progressive set-up, but not eliminate them entirely.

The player`s outputting as PAL50. I`ve a Pacific that does exactly the same thing unless I switch the picture output to NTSC (when it plays sweet as a nut). Does exactly the same thing if I play a PAL disc and it`s running in NTSC mode. It doesn`t have an AUTO setting. :/

The player can play both PAL and NTSC, but the TV can`t.

You see it`s 50Hz, which is ok for PAL 50 dvd`s but not NTSC, since they are 60Hz.

Only solution for me to either by new TV or a new cable, so I can watch the NTSC disks on my computer (which is better than my TV, due to that it is a LCD screen).

I will go for buying the cable, since my tv is not so old to be renewed and it`s cheaper to by the cable. ;)

Good solution or not???

Are you sure the TV can`t handle 60Hz? My old set couldn`t handle pure NTSC (3.58MHz), but it could do PAL60 (4.43MHz). Does the screen actually roll when you play 60Hz material, or is it just in blck and white? If it`s the latter, you can often get around this by using RGB.

I haven`t been able to find much info about your TV, which doesn`t help matters.

The picture from the NTSC DVD is fine, only it is slow sometimes, like it can`t follow the high frame rate, like it skips some frames to be in sync with the sound.

In my manual it says as follow:

Color-TV-System: PAL, SECAM
NTSC 3.58/4.43 (Video input ONLY)
The TV has following outputs to the screen (you select which picture you want to see):
1. SCART
2. RGB-signals through SCART (audio/video)
3. S-Video through SCART
4. Audio/Video through Video input with phonojack
5. S-Video through Video input with 4-Din Contact

TV inputs:
2 Scart on back
1 S-video on front (4 Din contact)
1 video/audio input (yellow (picture) white & red for the sound)

The NTSC is on the video inputs only, so how do I connect that the picture comes from the video inputs, based on the description above??? :/
Maybe I should use S-Video out from DVD and S-video in to the TV???

Please help me!!!

for anyone looking for a decent, slightly `tecchie` but readable website on the whole NTSC/PAL issue, try here

It`s probably a good few years old now (The talk of MAC as a satellite broadcasting method shows that!) but it`s still good information

What it means by `On the video inputs only` is that it`s not NTSC compatible via the tuner(aerial) connection-Some TV`s also have multiple format tuners, but most need NTSC to be fed via Scart, Composite or S video to be able to be able to correctly display NTSC.

Any of the scart connections on your TV should do the job, but you may need to make a manual adjustment within the TV menus as to whether it`s accepting PAL or NTSc. Most will auto detect, but some don`t-My old Schneider set had to be told it was getting an NTSC signal, then it played perfectly, if it wasn`t told, it would exhibit the same problems you are describing.
