I don't think it is an inherent problem with later IVTVs. I'm running
0.4.3 and the system started out with 2 150s and worked fine. It now
has 4 150s in it and still works.
One of the 150s is an "MCE" model, and I thus have a problem with the
tuner being recognized properly. If I use the normal fix of passing
the tuner type to IVTV I get the incorrect tuner on the 3 non-MCE units.
My "solution" is that I am only using the composite input on the MCE
card, and thus the tuner type doesn't matter, but I'd still like to
know if there is some way to pass a parameter to IVTV for just one of
And YES, we are all interested, as are the archives most of all. I'm
sure we have all experienced the frustration of finding a thread with
our exact problem which stops before the solution gets posted. Some
folks apparently lose interest in posting as soon as they get things
If we can pin this down to something repeatable the information
should also go into the WiKi.
Thanks for following up.
