The sample you have posted, plays fine on my unit... using auto resolution and match frame rate and also selecting 1080p 24 mode. Are you using the latest firmware? I am playing files back using hard drive only, no network shares.

Tried it with 60Hz, too? Because, as I have written, it works here in 24p, too.

I tested your sample and it indeed shutters. May be some folks do not realize that video should play smoothly in the sample. Of course, it is easy to see difference when you have different players side by side and one is playing it right. Dune Smart D1 - plays it without any stutter, very smooth. WD is not playing it right by far, even watching sample was a torture.

I am using 60Hz as all sigma based players have incosistent lip sync issues with different file types, resoution and etc. 60Hz seems to be spot on all the time.

I am having the same or similiar issue ///95% of my 720p mkv plays flawlessly ... 80% of my 1080p with or without any file compression stutters/freezses. I am playing from my hard drive , using the latest firmware.

This occurs whether framrate is set to match or auto ..

I've purchased this box since november , 8/10 1080p movie freezes .   

Hopefully this will be fixed soon .

I think they screwed something up in the latest firmware. Before this, I was playing 15mbps files just fine. Now I'm having trouble at 12mbps. I am thinking of downgrading and seeing if that fixes it.

And for the record, I'm using an NFS server.

when i have my unit set to 1080 60 the file uploaded doesn't play all that well, it judders. if i have match frame rate on or 1080 24 it is real smooth!

i agree somehting has been screwed up with the firmware.

judder on 60hz is normal its cause of the additional frames created.

your player is acting normal. peoples player that stutters is not normal.

Any other player, including WDTV does 24 -> 60 frame conversion nice and smooth. The difect is only happens during VC-1 24p MKV content playback. It plays the same content in m2ts with butter smooth 60Hz conversion. You can remux it to m2ts with tsmuxer and it will play just fine in 60Hz same exact content.

I remuxed the sample I've linked to (page 2) into a M2TS (with tsMuxer), and for me it's stuttering a bit (not a lot, but still noticeable) at both 60Hz and 24p, but not as much as the MKV played at 60Hz. The MKV played at 24p is stutter-free and smooth.

On the latest firmware (1.09.10) still stuttering @ 60Hz, no stutter @ 24Hz.
