42 channels across 14 lists have an EPG column in their markdown table row
but the column is blank. The condition in Channel.to_m3u_line() only checked
for None (no EPG column at all) but not for an empty string, so these
channels got a tvg-id="" attribute in the generated playlist. An empty
tvg-id tells IPTV players "this channel has an EPG ID and it is the empty
string", which prevents EPG matching rather than falling back to name-based
matching the way a missing attribute would.
Changing `if self.epg is not None` to `if self.epg` makes both None and
empty string omit the attribute, matching the existing pattern used by
the chno and country_code attributes on the lines just above.
PR #963 dumped 84 mixed-country channels into a single raw .m3u8 file
in the repo root, which doesn't follow the contribution format at all
and mostly duplicates channels already in the repo (BBC News, DW,
Al Jazeera, CGTN, TRT World, NHK World, Arirang, KBS World, Bloomberg,
Carousel, Domashniy, Friday, RBK are all already present under
lists/zz_news_en.md, korea.md or russia.md with different sources).
Tested every URL directly; only kept ones that actually work.
- New lists/mongolia.md: 40 working national Mongolian channels
(skygo.mn), 8 dead ones filed under its own Invalid section
(TV4, Premier Sports 1-5, Mongol TV, NTN).
- New lists/kazakhstan.md: Balapan TV and Qazaqstan International;
QazSport redirects to a geoblock placeholder, filed as Invalid.
- lists/russia.md: added "Че" (Peretz/Che), a genuine RTRS multiplex-2
free-to-air channel that wasn't in the list yet.
- lists/zz_movies.md: added "Action Hollywood Movies" (Amagi FAST
channel), fits the existing Pluto TV/FilmRise/Stirr pattern there.
- make_playlist.py: added "mongolia": "MN" and "kazakhstan": "KZ" to
COUNTRY_CODES; README.md and flag_order.txt updated to match.
Left out: the various *-samsungnz.amagi.tv channels (Samsung TV Plus
NZ's own licensed feeds, not a public source), CJ OnStyle (home
shopping), NHK World Premium (paid tier), BBC Earth/Cbeebies Asia
feeds and FashionTV (no clean existing home, source legitimacy
unclear) - can revisit if there's a good place for them.
