I have a load of video files, mainly mp4 files, that I have downloaded and would like to play via my PVR, however, for the most part the video does not display, and sometimes not even the audio.

I have tried converting some of these files to .ts and .m2ts but it makes no difference.

I have upgraded to the latest OpenVix version in order to see if that made any difference, but it didn't.

All the files play in VLC on my Win10 PC, whether or not I transcode them. An example of the VLC Codec info for one of them is as follows:

Stream 0
Type: Video
Codec: H264 - MPEG-4 AVC (part10) (avc1)
Resolution: 320x240
Frame rate: 25
Decoded format: Planar 4:2:0 YUV

Stream 2
Type: Audio
Codec: MPEG AAC Audio (mp4a)
Channels: Stereo
Sample rate: 44100 Hz

Other than the Resolution, this is the same video codec as ITV HD, although Original ID is not present in my mp4 file.

Have I just hit a limitation, or have I missed something?
