[mythtv-users] RE: [Xmltv-users] Figured out problem with tv_grab_na and long listings

[David A. Mason]

Well, I tried your changes once more, but against a CVS build of tv_grab_na,
and I'm probably matching your results.

Thanks a lot for this assistance.

Just out of curiosity, are you missing data for 170-176 (Nickelodeons,
Disneys, and Cartoon Networks) plus 168 (TNN, but who really cares about
that one?). Those seem to be the channels bringing about the failure without
your traps.

It's unfortunate, since, as a geek, my household is a Cartoon Network and
SciFi channel household, and now we won't have our proper balance!

This is turning into a real mailbomb, isn't it?
