Cases of blocked video and missing audio.

[mame]

The attached video-clip is the recording of what appears on the PC monitor (in the clip the shift between video and audio is due only to technical causes of recording and does not affect the substance of the problem exposed).

To help understand it, I list what happens:
- I am tuned to channel 1 and everything is OK.
- I set the tuning on ch.501, and here the video is blocked: trying various solutions, I have found that clicking on "Live TV" the video gets restored.
- by clicking now on "channel +" it is OK for ch.502 and then for ch.503 …
  ... but then on ch.504 and 505 and 506 there is no audio and a message appears;
  still looking for solutions I found that clicking on "Audio stream" and then on "ita" the audio gets restored.
  The message says "You don't have a MPEG1 decoder selected" but all decoders are just selected (as highlighted in the clip)!
- going now to ch.507 is instead OK.

What is it happening?

No attachments. If they're large, you probably need to put them somewhere like onedrive or dropbox, and let us know the url.

Did you view? nothing about?

Can you use the evaluation version of tscapture (from https://tscapture.com) to capture a 1 minute full transport stream from the channel 504? Put it somewhere like onedrive or dropbox, and let me know the download url. I'll try it here with my signal generator, and should be able to reproduce and fix for the next build.
