Yes, it was MPEG4. But I thought most MPEG2 receivers would detect it and play the audio. The Coolsat 7000 even identifies it as a video channel, but it seems to have kept turning up as a radio channel in other people's scans.
In late December, it was sharing a channel with Al Kalema as well as having its own channel. Al Kalema is now sharing a channel with CCN2 (whatever that is, it appears to be down most of the time) and the other channel has become something else, maybe Nacion TV but I'm not actually paying that much attention.
