[mythtv-users] Extracting QAM streams outside of Myth

[Preston Crow]

I've got Myth recording from QAM, but in going through and looking for
channels, I see dvbtraffic reporting a number of different streams, and
I would like to be able to save a bit of each stream and try to figure
out what it is.  (Might some of the low-bandwidth streams have useful
data?)

Is there some simple tool that I can use to save a given stream,
regardless of the contents?
