I am finding that my mp4 files (aac or mp3 sound) are juddering on the WDYV Live.
I also have the WDTV - NO judder!

I wanted to buy the WDTV Live to see what it could do.

Why the change

thanks for the reply, I thought that the WDTV Live would (at least) do everything that the WDTV did.

Little bit disappointed in WD

Hmm... I guess I may have missunderstood the OP.  I understood it to mean the video because that's what judder usually refers to.  The OP can chime in and clarify, I suppose.

It might help to post more details... this is one of the videos I'm having problems with:

As I say, it's the video, not the audio I'm having issues with.

Edit:  I should have included this in the OP; another post reminded me it could definitely make a difference:

Yes, I played a couple of mp4 movies last night, audio and video were great, but the audio would (as you say) judder every minute or so.

Mine just started doing this (or more likely I just noticed it) and I can't figure out why.  I was assuming it was my wireless connection dropping bandwidth, but I'm not too sure now.  Are you wired or wireless?

I'm playing a 2.1gB .mp4 and the audio drops out for a split second every minute or so.  After reading this post I downloaded a higher quality .mkv file and it streams flawlessly.  No audio dropouts at all.

I am playing directly from the USB hard drive.  I haven't taken the time to analyze the format/contents of the MP4's, but (in general), it seems that the MP4 movies I play experience the 'judder'.  I have played some very large and nice quality MKV videos, and they play perfectly.

Well, at the very least I know it's not my wireless connection.  Good to know.

Hopefully this will be one of the bug fixes in the first firmware revision the WD guy mentioned on the other sub.

I had mentioned this problem in another thread but got no comments or suggestions. I see the judder or stutter whatever you want to call it, every 10 seconds or so. The following file exhibits it pretty clearly when viewed on the WDTV Live. Unfortunate because otherwise, the clip looks and sounds great.

What I ended up doing is demuxing the file (see previous post), stuffed it in an MKV, and it works smoothly now.  It's possible mp4 with subs stutter on the Live?

Anyways, your mov file seems to have a similarly odd appendage at the end of it.  Dunno, maybe you can remove it?

Good luck.

I have the same issue, but, I've found that the issue goes away if you rename the file's extension to .m4v

But then, you can't rewind or fast forward, and the sound is a little out of sync.

Here's some mediainfo data on one of my former .mp4's (all of which were converted from MKV to MP4 using Gotsent):

So you make it watchable by making it... unwatchable?  ???

Just have a toilet break before watching the video.  ;D

More watchable then having frame-drop-o-vision.
