LOL, As stable as CX88, you must be joking. As far as the number of developers on the card, if you are as capable of reading what you claim, you can see that from the changelogs, in the main tree itself. You mean the SAA7146 driver is young ? Hmm.. pretty ignorant comments, you seem to make. The 7146 is one of the oldest driver that exists. Exception is bttv which is still older. > Also considering the fact that none of these > drivers even report signal stats properly. Then, of course, there's my > recent experience with your SkyStar HD2 driver. :) Which card are you talking about ? Your experience with the Skystar HD driver == USER Error, that's what some people would think. The mantis driver is a driver which is very much in development. You should've read it on the ML's itself. It's really sad that you are pretty much ignorant. A driver which is in development, you expect all sorts of issues. That's why it is in an external tree. Now, you managed to get hold of the wrong tree, burned your demodulator, inspite of me warning users on the ML's many times. So you are still ignorant on that. You decided to do, what it pleased you. Not my fault. I guess, you don't understand the term "Development", "Stable" etc either. The TT S2-1600 support is much different, support for it exist in the mainline tree, which is verified. The SAA7146 bridge which the S2-1600 is based on, is the most mature PCI multimedia bridge that exists under Linux. Also you seem completely ignorant about how Linux development goes on. > You have to > understand that me, in this case just a common user, do not wish to > invest into a product with an unfinished driver.

My opinions are my own. I don't care about your completely non-technical or trolling posts. Whether Technotrend is having a new ownership/management is as well nothing of concern to me. There seems to be people buying the"dead product" that you claim and hence the support for it is in. > Nevertheless, I tried to get the data-sheet for this dead product from > their closed down & discontinued sites.

You can look at the STV0903 specification, or the announcement that i made earlier on the list about the same. >From the Cut 2.0 chips onwards, The STV0900/903 demodulators do support 45 MSPS officially and unofficially 60 MSPS with 8PSK modulation. Anything predating Cut 2.0 you don't find on any PC related products. http://linuxtv.org/hg/v4l-dvb/rev/4882c97b0540 > Pretty standard specs, if you ask me.

When you are ignorant about technical aspects, you don't do a technical discussion. You seem to be an ignorant troll.
