Hello there,
Wonder if anyone would be able to help with this problem -
Basically I'm in the UK & have just bought a WDTV Media Player (Pal version).
I've been ripping my dvds to the mkv format using MakeMKV.
All my Region 2 dvds have been fine - correct aspect ratio & all play fine.
Now I've also got a lot of Region 1 dvds.
These rip fine & play smoothly when tested on the pc, but when playing back via the media centre, they jerk every second.
I'm guessing this is because the media player (for some reason) is playing the ntsc 29.997fps file at 25fps & the dropped frames are causing that slight jerk.
Avi files & vob files don't seem to have this problem, but due to the amount of R1 discs I have, I can't afford to spend 3hrs+ per disc converting to avi files & vobs tend to display at the incorrect aspect ratio (ie squished - see picture at bottom of this text for an example of how they display on the tv).
So my question is -
Is there a way to get this unit to play the ntsc mkv files correctly so there's no jerk?
I did notice a Pal setting in one of the video menus on the unit, but I can't change it to anything else. I would have thought they'd be an Auto or Ntsc setting as well, but no amount of clicking will alter the Pal setting.
I have the unit connected to the tv via a 1.8m hdmi lead - although I can't see it being the leads fault.
Thanks.

As far as I recall the PAL/NTSC setting is only enabled when connected via the composite connector.

R1 disc - freshly ripped to mkv.
Ram the mkvmerge prog, altered the fps to 30000/1001 (originally tested in media info & it was 29.997fps).
This one didn't play properly - infact the audio was well out & took around 10 secs to actually start playing - thought I broken the machine to begin with!
Also tested a H264 .mp4 video which was 23. fps - this one seemed to play ok, so at least I know these files can play properly.
So it may have just been a bad test on the R1 disc, or possibly due to the framerate.
Will do a couple more tests over the next few days.
Thanks for the info so far though everyone -
Ok, solved it (sort of).
If you click the HDMI section in the media players menu & select 720p 60hz (or higher res if your tv is capable), it'll play both R1 & R2 mkv rips perfectly
Also plays mp4 24fps files fine as well. -
It's very odd that changing the HDMI output setting would effect A/V sync. What was it set to originally?

It was originally set on Auto. -
I guess there's some firmware bug that caused it to lock the playback frame rate to 25 fps. After a while (once during each GOP maybe?) it saw the 30 fps video was falling behind and skipped a bunch of frames to catch up.

Maybe. At least it's playing nicely now which is the main thing

i get the same problem
just go in to your WDTV and change the resolution to 1080p 60herts refresh rate. this WILL work coz i do it all the time.
simple
