Hello, I'm having frequently "Unknown audio decoding error", "Header missing", "ac-tex damaged" on what seem to be all SD channels, which resutls in prebuffering pause in MythTV. All HD channels are fine and no problems. The channels which are worst are also very hard to lock. Sometimes some channels are not watchable at all. I am using Canal Digital in Norway, channel listing can be found here: http://www.telenorsbc.com/templates/Page.aspx?id=678 I have had this problem for about a month. I know that Canal Digital have done some changes to the transponders around the same time that this happened. But I don't know if this has anything to do with it. I have deleted all transponders and channels in MythTV and rescanned everything. It seem like a bad signal, but when testing with the set-top box from the provider it shows signal strength 80% and signal quality 90%. Also it is strange that all HD channels would work fine if there was a poor signal. * I got a Hauppauge Nova-HD-S2 card. Using Kernel 2.6.30.9 and MythTV trunk revision 22257 * My dish is pointed correctly using a satellite finder. it shows 9 out of 10 when the db button is set at the lowest. This is the best signal I have ever had. I've tried to slightly adjust the dish anyway without any change. * I have replaced the LNB, it is a Triax Quad LNB. * I got two cables from the dish, same problem with both cables. * In MYthTV signal is shown as 85-86%. BE is 0. This is the same as I have always had when it was working. I have also tested with a Technotrend Budget S-3200 card, which had the same problems, except that this card does not work on HD channels at all, which it never have. Here is the log when this happens: 2009-10-08 15:58:43.381 mythfrontend version: trunk [22257] www.mythtv.org 2009-10-08 15:58:43.406 Using runtime prefix = /usr/local 2009-10-08 15:58:43.406 Using
