Hello,
I have found to problems, first mplayer and me-tv are unable to lock the signal, kaffeine, tzap, xine and vlc are working fine. I'm using Ubuntu 9.10
mplayer: 2:1.0~rc3+svn20090426-1ubuntu10
me-tv: 1.0.0-1ubuntu1
second problem appears when using more than one card. I have another Avermedia E506R that is working quite well under Linux. When I insert it before I plug the Sundtek Gold it gets detected as dvb/adapter0 and then when plugin the sundtek it correctly appears as dvb/adapter1, but when I plug the Sundtek first and then the E506R everything gets broken. I only get one dvb/adapter0 that seems to be a mix of both cards. I suppose that /opt/bin/mediasrv isn't notifying the kernel or whatever that the dvb/adapter0 is already assigned and the kernel reassign it to the E506R. This is a low priority bug (at least for me), but I report it.
Anyway I prefer you start ironing the problems in Windows drivers. Right now I'm not able to get any channel under Windows Media Center.
