Good points. I am a big fan of having stuff locally as well, because I don’t
want to be dependent on a company’s servers and a working Internet connection.
But this mostly applies to my mobile device, because I don’t have a data plan
for mobile Internet.

I wasn’t aware that ts could contain h264. But then again—I never really
bothered with live TV recordings in recent years. These days, if I find
something interesting, I download the show form the TV channel’s website
(called Mediathek in Germany, a word play on Bibliothek, meaning library).
Interestingly though, the picture quality is noticably worse than what I
receive via DVB-T.

Naturally, I just discovered two bugs in the script while I was re-reading
my mail. One of them broke the creation of the symlink which points to the
most recent version of a script output. The other prevented normal operation
if only gzip was available amongst the used compressors.
