This is a recording from ČT2's digital terrestrial broadcast. I decided to use it here to demonstrate the results of the "restoration" done on the below DVD release. As you can see in the examples that follow, both version come from the same source, FEX, however, got rid of the biggest damage - simply by deleting the "bad" frames, and duplicating the "good" ones. I've got no knowledge of how the restoration of such deteriorated material could be done, if at all, but I think the approach employed here is not the best...
