Teletext in South Africa
See that MNET transmits Teletext (called M-BEAM) during open time as they've got some holding page in place. Actually it looks like they have just installed the software and left it in its default state hehe. But alas nothing useful other than the sample page on there.
Only SABC2 actually offers the service with anything useful - got TV schedules so at least you don't need to refer to the Sunday Times magazine all the time.
