I think I bought it 2006, not quite sure when exactly. I think what killed it was that it was working permanently for 1,5years, so it probably overheated somwhen in the summer.

I'm using now terratec for about 30€. There were again problems with the drivers so I'm compiling again the v4l-dvb code. I don't see anything wrong to do it on your own. regards -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Thanks for the heads up, I think I'll have a look and see what else is available out there then, luckily I only borrowed it to test if it would work.

I have a similar situation with Pinnacle Hybrid Pro 330e (yes, 3_3_0e) : the only driver that works (and was great at it) was Markus Rechberger's em28xx-new project. (my device has cx88 tuner IIRC). The em28xx-new project had some modifications to some tuner drivers too. They were based both on RE and documentation for which Markus had NDA's signed (a vague recollection of past googling). The mainline kernel unfortunately does not support it out of the box, and it is not only about the firmware you have to download; There is something severely nonfunctional. Why am I writing in past tense ? This driver (em28xx-new) has recently been abandoned, and its author went proprietary. I was using a ubuntu package prepared by some ubuntu user, named gborzi.
