Hello linux dvb gurus, I've got the following setup: 1. current Mythbuntu 9.10 ( kernel 2.6.31-16-generic-pae ) 2. current v4l-dvb drivers ( freshly checked out from http://linuxtv.org/hg/v4l-dvb ; I've also tried with Liplianin drivers from http://mercurial.intuxication.org/hg/s2-liplianin with the same effect ) 3. a TwinHan VP-1041 DVB-S2 card. My signal comes from ASIASAT-5 satellite. You can see all the stuff this satellite provides in http://www.tvro.com.tw/SATELLITE/100.5/100.5d.asp ( the page is in Chinese, but you can see it has - among others - two transponders which I am going to talk about , one is at 4000H freq 1150 sr 28125 fec 3/4 and another on 3960H freq 1190 sr 27500 fec 3/4 ************************************************************************************************** Now, I want to stream a whole transponder via UDP. So I try with a first one: $ dvbstream -c 1 -f 1150000 -s 28125 -udp -i 224.224.224.1 -r 1234 8192 dvbstream v0.6 - (C) Dave Chapman 2001-2004 Released under the GPL.

I've connected a satellite set-top-box to the signal and the STB can tune to and watch channels from both transponders with no problems at all. That IMHO proves that the signal is all right and the problem lies in the drivers, or maybe in dvbstream. ( or hopefully between the chair and the keyboard ) 2. I can ONLY tune to the 'freq 1150 / sr 28125' transponder. All others fail. But with that one I have no problems at all, I tunes 100% of the time; I got it to stream for 4 days straight with no problems. 3. You can see that both transponders are C-BAND , H polarization, so theoretically, AFAIK, if I can tune to the '1150' transponder, I should be able to tune to the '1190' one with no magic at all, am I wrong here? Could anyone shed some light on this? best, Leszek -- 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
