[mythtv-users] Recoding in native TS format and Setup with ATSCas DVB card

[Andrew Chung]

I'm currently using the DVB drivers and they seem to work pretty well at
this time.  I think our channel scans would be a little different since you
probably chose a different input card than I did.  Perhaps the Video4Linux
input type instead of the DVB type.  Is that correct?

Not used the Myth channel scan, but I took the slightly different route of
manually pinning down all the channels with dtvscan /dev/dtv, then building
a profile on zap2it, then manually tweaking the  channel values until
everything tuned properly in myth.

I'm on the CVS from about 5 weeks ago, but still using the HDTV drivers
rather than the DVB ones, which I couldn't get to work.
 



Andy,
    AFAIK myth does record from ATSC cards in either
ts or ps, the nuv extension doesn't affect what the 
file actually is.
file 2005_20050427220000_20050427230000.nuv
2005_20050427220000_20050427230000.nuv: MPEG transport
stream data

I record mine using .ts simply because my box is
underpowered to begin with and I think that recording 
in .ps involves more processing but a smaller file.

I think you are on the right track for your channel
setup.  What I did was have mythtvsetup scan for the
ATSC channels in the channel editor, added the xmltvid 
from the zap2it channels to the scanned channels and
then marked all of the zap2it channels invisible so
that only the scanned channels show up in the program
guide.
