Hi Matthias, did you try to reload the driver? Markus On 9/29/06, Matthias Thomae <bluez@xxxxxxxxxxxxxxxx> wrote:

My problem occurs with vdr *and* kaffeine, and, what's more, the same problem occurs on Windows with both Terratec TV applications. > Usually, the symptom with vlc was that I had to switch to one of ARD's > channels (Das Erste, arte, Phoenix, EinsPlus) as the *first* station after > plugging in the T2, otherwise switching to it from another frequency would > fail. This is different from my problem, where initially tuning works perfectly, but after a varying amount of tuning it starts to fail for certain channel transitions. In detail, switching to a channel in the ARD group (frequency 184000) works from these channel groups: 778000 (z.B. Bayer. FS), 786000 (Eurosport), 834000 (RTL) but fails from these channel groups: 578000 (ZDF), 626000 (Pro7) > After a great deal of experimenting, I found an astonishingly simple fix: > *Get a better antenna!* As soon as I connected a better antenna, switching > back and forth between channels worked fine in vlc. My antenna looks like > this (more or less): <http://www.yucel.de/max/DVB-Zim.Ant.jpg> I also had this hypothesis, or rather the one of a too weak signal, although I get signal strenghts of 70-75% as mentioned above. Yet, I already have a good antenna (a log-periodic Wittenberg WB345), and I even got an amplifier which improved reception a little but still I have this problem. What's more, I also got a different DVB-T Stick (Pixelview PlayTV 505) which doesn't have these tuning problems. > I noticed that (like me) you seem to live in Munich.

I live in the vicinity of Nuernberg, and here ARD is quite strong (70-75%) compared to RTL for example (55-60%). > Still, it is weird that kaffeine works fine.
