Just to throw this out there, the 'doze support for one such Micronas-based device I have -- the Linux kernel support for which either does not exist or cannot be publicly distributed -- is less than optimal in my experience, which may have nothing to do with reality. While I was able to make a flawless test recording for a few minutes of one medium-bitrate lower-resolution high-definition programme to mislead me into thinking that I'd have success with a full-length programme, for some reason it turned out that my use of the device under 'doze for an extended time on a borrowed 'doze box suffered fairly frequent problems manifested each as a short dropout of the recording. This could also be pilot error, as I remain willfully ignorant of 'doze and its details, but if a machine with CPU horsepower over eight times that (neglecting other acceleration) of my workhorse that routinely makes four simultaneous flawless recordings including some at higher resolution/bitrate, is unable to keep up with the bitstream, then something has got to be seriously wrong, in my opinion. A later recording of a higher bitrate (excellent quality standard- definition video source) stream again exhibited the same problem. Perhaps 'doze can't keep up writing to its own native filesystem as it approaches being full, or if I can't keep my hands away from configuring it to be user-hostile as I prefer. And of course there's the factor of intermediate hardware to be considered -- my device is connected via a USB interface which has caused major filesystem corruption over time with the particular Linux kernel I was using, despite of working flawlessly with a different video card. And 'doze... *shiver* Anyway, I'd be happy to learn that others have had success with the same device, although for me it's no longer a priority to have it working, to say nothing of working perfectly. My testing of the device has been relatively minimal, using it where other tuner cards lack support. barry bouwsma -- 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

" It is important to notice that the vendor (Trident) doesn't seem to want helping with open source development. Contacts with the vendor were tried during 2007 and 2008 in order to get their help by opening docs, via Linux Foundation NDA program, without success.

I've added it to the linuxtv.org wiki (http://www.linuxtv.org/wiki/index.php/TechniSat_CableStar_Combo_HD_CI). It seems the Windows drivers for this device are very similar to those of the (supported) Terratec S7 DVB-S device. No quite sure that to make of that, though. The Micronas DRX series seems to 'evil' in that there is only a closed-source driver and the manufacturer doesn't cooperate with open source developers.
