Hi John, Rex, As an extra data-point: John's patch worked fine for me (Quad LNB with integrated switch for Astra-28.2E). I'd really like to build on John's patch to work up a full fix. To do this I'm trying to track down a cx24123 datasheet. I don't suppose either of you guys has a pdf? cheers, Andrew -- 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
