But if this is over DLNA then nothing wrong here. Seems to confound folk new to this. There are open discussions about file naming and encoding so I'll stop here.
Any idea why I have .mp4 movies which are in a directory on my PC and can be seen on the PC, but not via the TV.
If I copy one of the "missing" files to a USB stick, it appears immediately and can be played.
Is there a limit on the number of files which can be in a directory on a PC?
