I can't help with most of this, since I do not use the hardware you use,
and I am not familiar with how tvtime labels things. I limit myself to
answering a couple of the specifics you asked about (and even that much
only because I have seen no other replies to this ... I really doubt I am
the most knowledgeable person here with respect to your problem).
I do recall in the past seeing some threads on the Leadtek card, so you
might find it useful to search the list archive to see if they contain any
helpful advice.

Neither am I, in tvtime. But usually,
"television" is associated with the RF signal, coming on on a coax
jack, that is tunable to specific channels
"composite*" is associated with an NTSC or PAL composite signal,
coming in on an RCA jack, that is not tunable.
On the vidcap cards I have used (A Hauppauge and an AverTV), the sources
were Television and Composite1. Television was source 0.
From your comments below, it does sound like your test tvtime setup ... or
perhaps the v4l driver itself ... is somehow mixing up the inputs. Its use
of "composite0" is certainly consistent with that sort of mixup, but I
can't help you with the details.

I don't understand this. "everything works fine" and "I cant see any
difference" seem to be contradictory statements. Anyway, since you don't
tell us the details of either system's hardware, we are unlikely to be able
to suggest any possible hardware problems.

This description is what makes me think that your tvtime setup is in fact
associating "composite0" with the RF input source.

Does Myth (not tvtime) really report both a "Composite0" and a "Television"
as available to you? Does it behave the saem way as tvtime with respect to
use of these inputs?
Try reporting here how the source-identification problem manifests itself
in Myth and you might get better help.
