Here in Spain there is at least one station (TVC's 3HD) emitting HD content through TDT, and it works flawlessly with a Nova-T 500 (as I have one). I'm not sure if contents are 1080 or 720, though. There were some problems watching these channels through MythTV, but they were definitely decoding related. With current MythTV trunk they are fine. Anyway, as I said before, theoretically a DVB card doesn't know what kind of streams contains the signal it tunes. Decoding & parsing is handled by the app. Best regards, Eduard Huguet -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
