MHZ is over the air in the DC area, with a pretty good mix of shows. Some Aussie Rules, Italian football as well. But also some international mysteries and tons of news programs in multiple languages. I used to watch some Euro Dance show on there on Saturday nights (believe it or not, it was the first time I ever heard of Brittney Spears)
The MHZ feed that was FTA was not always the same as that which they showed OTA though. They blocked out some shows on FTA with a repeating advertisement that was quite annoying. Guess they didn't have the rights to distribute certain things over a satellite.
I have globecast and only subscribe to Setanta Sports, however on the globecast receiver MHz comes in. On my Traxis3500 it shows to be scrambled. I suppose it is currently available to anyone with any type of globecast sub. It will probably change in the future.
