Yes, the chinese content on SatMex5 is GONE. However, there are a few EXTRA channels that I have not seen before on SatMex5 but is now on SatMex6. They are
CCTV4 (but I already have that on G3), ATV (great cantonese channel from Hong Kong), GDTV (just showing text right now), ETTV AMERICA, ETTV GLOBAL, ETTV CHINA. SUN-TV has been gone and replaced with a "VIDEOJET" logo. What is the same is the 2 Phoenix channels, MAC (Taiwan), the 2 budda channels, and IFTV (christian chinese).
SatMex6 is definately where most of the chinese content is right now, more than G3 and
IA5 (NTD).
