I use a WDTV Live (WDTVL) to play back standard def recordings produced by a MythTV 0.24 backend machine (Athlon 3.1 GHz PC running Mythbuntu 10.10, Hauppauge PVR-150 MPEG capture card).
The MythTV backend shows up in the WDTVL interface under Video -> Media servers -> mythbackend1: MythTV AV Media Server. The standard def files that are recorded by the MythTV backend are multiplexed MPEG-1/2, and they have a file extension of .mpg.
These standard def .mpg files play just fine on the WDTVL - no problem at all.
I have just gotten an HDHomerun (HDHR), which I use to capture the local over the air digital stations and (I had hoped to) watch them on the WDTVL. I have set up the mythbackend to record shows with the HDHR, and the shows record fine and will play back fine in VLC on both my Mac and on the mythbackend machine.
Like the SD files, the files that the HDHR produces are multiplexed MPEG-1/2, and they have a file extension of .mpg. But they will *not* play on the WDTVL. I try to play them, and it fails with the error “Unable to play the selected file. Please see the user manual for a list of supported file formats.”
The files are of a supported type: they’re mpeg files, and they’ll play just fine in VLC.
So, any idea what may be causing this?
