Well, I wrote szap at a time when the DVB API only supported DVB-S
(for the first generation av7110 based Siemens/Technotrend/Hauppauge
DVB-S cards), because I needed it for my work at convergence integrated
media GmbH. The S in szap was supposed to mean "simple". It started
as a really tiny testing tool.

Later Holger added tzap and czap. Needless to say that I would've
integrated T and S support into szap right from the start, but there
was nothing I could do about it.

So there's no technical reason, it's just a historical artefact.
