It is too early to give up now!!1! At least, I shall not give up until the sun melts away enough of the snow, so that I can go out and get more beer, though the melted snow will probably freeze into slick ice, and I'll probably end up hurting more than last time, this time with broken glass embedded into my body... A direct infusion of that evil alcohol into by bloodstream without the middleman of passing the lips, gums, tongue, nose -- heck, why bother searching to find excellent-tasting beer when I won't notice and appreciate the difference anyway... > i used to have this card running in a dual boot with windows xp, where > everything worked like a charm, and another one where i kept installing linux > distros without any luck until "kubuntu hardy" came out.

I even replaced the T connectors, just in System `upgraded' and stopped DiSEqC working; but also, system moved. No success since then. Question: When you moved the system, did you have to add new cable? If so, how long was the length of cable from your machine to the DiSEqC switch before you moved it, and how long is this cable now, or is it the same length and same cable? Other question, what do you mean by a `T connector'? For satellite, I am familiar with the `F' connector, and I am also familiar with other types of `T' connector, but they should have no place in a satellite system... > so... is it possible that somehow i've broken the card someone? the truth is Not too likely -- DiSEqC switching is basically the same as a modulated version of the 22kHz tone which is used to switch between low (below 11700) and high (above 11700) frequencies by the LNB. However, I have had experience with several different 2/1 and 4/1 DiSEqC switches at the end of long cable runs, which could not be properly switched by some DVB-S cards, but could -- or could not be switched by a consumer satellite receiver, but which worked flawlessly when located a few metres from the receiver, instead of nearly 100m away. The cable length attenuated or otherwise corrupted the DiSEqC bursts from some devices so that they failed to work. > that what used to work in windows... doesn't work anymore... this evening i > went back to windows just to check if the card, the diseqc and everything was > fine... and i had so many problems to get the satellite working as before. i > used to use progdvb, which supported diseqc for my card and now it just can't > tune through diseqc, none of the two satellites. other software does know how > to get through diseqc, but only switch 1. So, the same setup, apart from being moved, now no longer works the same as it used to work with 'doze, and 'doze either no longer works at all, or fails to switch DiSEqC? Note that a typical DiSEqC switch will simply pass along its 1/2 or 1/4 or 1/8 or 1/whatever input, when it does not receive the switching signal to select 2/2 or whatever. > i've checked cables and i don't think it's an issue from the diseq thing, > cause i've got two and both give the same problem. Two? Two what -- DiSEqC switches, two cables to switches? Do you have a normal consumer satellite receiver, as well as your different computer boxes? I'm going to guess based on where I think you are located, that you have something like the following -- please correct me where I ass-u-me wrong, and add any additional info that is missing from this... Dish+LNB pointed at 28E, large enough to receive BBC/ITV/etc Dish+LNB pointed at 19E (or offset mounted on 28E dish) DiSEqC switch(es) located near dishes -- or near your tuner so you can connect directly from each LNB as a test? Single cable run from switch to computer, or two cable runs from two switches? LNB19E-- \ long cable run 2/1 DiSEqC----------------------------Computer / LNB28E-- You also mention DVB-T/radio from this card; if you could mention how that affects the above, if at all (it should not, but I never know for sure) Also, if you have any spares (a pile of DiSEqC switches, other DVB-S capable cards, etc), it would be handy for me to know -- in the case of my 4/1 switches located more than 50m from my tuners, it was partially a case of swapping in other switches from my pile of them until finding a working combination, or running an additional several hundred metres of cable to permit me to switch the four positions close to the tuners... thanks, barry bouwsma not an expert, by any means _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
