Description

Some (!) videos cannot be downloaded. This is an example:

https://www.ceskatelevize.cz/ivysilani/12607522764-stardance-x/219544160450002-stardance-x-kdyz-hvezdy-tanci

It may be DRM issue, because I had problem to see it in chrome on Linux - they stated, that my browser does not support DRM. But after few minutes it worked - perhaps some timing problem.

This is another example - part of problematic video - and it CAN be downloaded without problems.

[remitamine]

some code to skip DRM protected formats has been commited wrongly as part of 07154c7.
