    I have just applied the latest CVS (02-28-2006--01-10) and have noticed that it now takes close to 10 seconds to change DVB-T radio stations. Previously, it was almost instantaneous (less than 2 seconds).

    There is nothing in any of the log files to show what is happening, but it seems odd, as the DVB-T TV station changes are still very fast (less than 1 second). So, it would seem that a recent change to My Radio is causing this excessive station changing delay?

    Hmmm - looks like I am the only one experiencing this problem....:(

    Anyway, here is the section of the MediaPortal.log file that shows the 10 second delay:-

    Notice how it is waiting for "pmt:-1" for 10 seconds? I have no idea what that means, but that seems to be the delay in hearing a new station, or switching to an alternate station?

    Just to let you know, you ARE NOT the only person this is happening to.

    Will post system details when I get on the system (definitely should install vnc on it).

    Happens to me with DVB-T Terratec 2400i, and CVS 15-03-06. Removed installation of Media Portal, reinstalled, applied CVS, registered filters again; still waaaay slow channel changing.

    I also, get the "no signal" problem occasionally. Pity, because the picture quality is superb when it works.

    Also, left PC playing full screen TV, come back 2-3 hours later and MediaPortal has exited; must have crashed because there's no task bar/start menu.
