Description

I am with facing a PMT table whose services share audio and video PIDs.

Although everything seems lost, I realize that VLC seems to separate PIDs more or less adequately even if they are incorrect, even marking the services as encripted.

While tvh only marks one service as encrypted. I think there may be something wrong in the processing of the tables. Even knowing they are out of regulation.

Service 5940 and 5950 shows as scrambled on VLC.

But on TVH only 5940 is scrambled .
