[mythtv-users] Trying to use webfrontend to view recorded shows from another network

[D&R]

web browser if firefox on fedora 30.

I have converted the ts files to mp4

ts files will play from mythfrontend but not in webfrontend

mp4 files will play from mythfrontend but in webfrontend I get video and NO
audio and only when I use the download option. play in browser does not work.

Is there a setting I have missed setting?

Is there a format that plays in both mythfrontend and webfrontend and if so,
what is it and is there a setting so that the file is saved in that format when
it is originally recorded.

Thanks in advance,

David
