[mythtv-users] No EPG data

Try turning on verbose "eit" debug (--verbose eit).  0.20 versions of Myth have a bug in the ATSC/EIT code where it decides the guide data should be hidden for most channels.

The check is along the lines of "if GuideIsHidden" and really should be "if IsHidden AND GuideIsHidden".   It is fixed in the 0.21 source tree.  In the ATSC specs, the "guide is hidden" bit is only valid if the "hidden" bit is also set.

0.21 sources also seem to be more accurate in getting the guide data associated with the correct show and channel (though I have only been upgraded to it for a couple weeks so I can't be 100% positive on that, I might just not have noticed yet).

This page shows a hack to the 0.20 code base if this is your problem:


Though really the correct fix from the 0.21 code base is to change the if statement rather than remove it to:

    if (vct->IsHidden(i) && vct->IsHiddenInGuide(i))

Yes they have.

Am I right if I say that MythTV picks the EIT data from program stream
by it self?

How could I confirm that I get EPG data?
