PlayOnLinux/CapTvTy issues when upgrading Sparky6.7 to Sparky7.2

[Changala]

I don't think this is the right category to load this post, but let's start here.

I am used to download my favorite TV shows to enjoy them better at a quieter moment than live, so I run CapTvTy in PlayOnLinux.
So far to PoTolo, so good.
A full system-upgrade from PoTolo to OrionBelt worked fine, but left a major problem, I can no longer download from some of the TV channels, only a few of them, unfortunately my favourites.

What I did before calling for help:

1) wiped a spare partition and made a clean new installation of Sparky7.2, PlayOnLinux and Captvty.
Same issue, can't download from some TV channels.

2) wiped again this partition and made a clean new installation of Sparky6.7, PlayOnLinux and Captvty.
Great, all TV channels download normally.
- I notice in the task-manager, that the channels that fail to download in OrionBelt, transfer mp4 files with curl, all other channels that still work under Sparky7.2, transfer ts files without the help of curl.
Then I made a full system-upgrade from PoTolo to OrionBelt, successfully, all TV channels download.
- unfortunately, insanely, after the recommended "sudo apt-get autoremove", all the mp4 TV channels hang again.

There has been 127 system components removed by the clean-up, probably only a few of them still needed, but I have no clue which ones and how to. Log here below.

Thank you
