With this driver I still have problems to use kaffeine (I already posted about it in a response to the driver version from February 11). As soon as I try to watch Digital TV (DVB-C) or press the button to scan for channels, kaffeine hangs and does not react any more until I kill it. With the driver version from January 25 everything works just fine.
I am using Ubuntu 09.10 with kaffeine version 1.0~pre3-0ubuntu1~karmic1~ppa1. The strange thing is that me-tv and gmplayer are working fine with the new version. However, these two are not nearly as comfortable as kaffeine.
I'm a bit frustrated as I bought the rather expensive sundtek stick because of its good linux support and now it is again a permanent hassle.
