Should Astra1H's ZDF crash my FS Omega?

[JetSetTed]

I'm trying to receive the ZDF FTA channels on Astra 1H's 11.954 GHz frequency -- but when I scan this transponder, my Fortec Star Omega puts the TV channels into its radio list, switches to ZDF (in radio mode), and then enters an endless crash-reboot cycle (which thankfully I can interrupt by switching the receiver to a TV channel from a different transponder.

Well, I don't think any signal should crash my Omega's software, but what do I know?

Other German FTA channels work fine (for example ARD Digital's, RTL's or Pro.Sieben's) -- why does the ZDF signal confuse the Omega?

Thanks for any clues,

Still the same problem no matter what I do.

Well, I've sent off a request for info to tech_support@fortecstar.com. Let's see whether there's any response.
