Hello, i have a Technisat SkyStar HD2 DVB-S2 tv card and it is working rather poorly on my Linux Ubuntu 11.04 system (Linux Kernel version 2.6.38 that is shipped via the official Ubuntu repository) Scanning for channels worked. TV programs show up, but they're out of sync and audio shatters extremely and runs jerky. Recording the TV program or just watching it is a waste of time because of the above quality problems. I tested several dvb player software like mplayer, xine, vlc, kaffeine and totem (with dvb plugin) but all have the same problem. On Windows this card works perfectly with the dvbviewer application. On http://linuxtv.org/wiki/index.php/Azurewave_AD_SP400_CI_%28VP-1041% 29#Identification i found the following text: > Note also that a different subsystem ID for a Skystar HD2 (1ae4:0003) > has been reported for some cards at > http://www.linuxtv.org/pipermail/linux-dvb/2008-July/027261.html so > perhaps a change needs to be made to allow for this possibility too. and i also read the additional mailinglist report: http://www.linuxtv.org/pipermail/linux-dvb/2008-July/027261.html http://www.linuxtv.org/pipermail/linux-dvb/2008-July/027279.html And i can confirm that, what is in this report. My Skystar HD2 has the ID (1ae4:0003) too. lspci -vv 05:00.0 Multimedia controller: Twinhan Technology Co.

Do you have any ideas to solve that?
