Trouble with some MP$ and MKV's

I’ve been using mine for about the last five years, streaming MKV’s, AVI’s and MP4’s without any issues but recently some of those formats it just won’t play and says it’s unsupported. I never had this problem before, any reasons why this is happening all of a sudden?

Are they the same files that used to play or new ones?

All of these are containers that an hold lots of different codecs some of which may not be supported by the WDTV.

How can I tell what codec it is so I can compare it to working ones?

mediainfo (free) 

untick the boxes if you don’t want the extras.

I jsut used MediaINfo to compare one of the mp4’s that doesn’t work to a working one and its the same codec “AVC1”

What about some of the other settings - like bit rate, etc?  Are they all the same too?

FYI,View → Text in Mediainfo allows you to mark the entire text and paste it here rather than a picture with half of the entries.

I’ll psot the full text later, thanks.

Finally got it figured out after some googling. Not sure why all of a sudden header compression is enabled on these downloads but following the steps in the link worked perfectly

Hm, I could not find any

Muxing mode : Header stripping

in your pasted text. Also, this has been fixed quite some firmwares ago for all WDTV models.
