Hello, if I on Sat.1 or Pro7 switch and the DD-Track select am all ok. If I shift back then to example RTL (non DD-Track Channel) and then again to Sat.1/Pro7, I have again the DD-Track. Thats ok. On ZDF and Arte is not however like that. There the first audio track one selects again and again. The VDR does not "note" the attitude unfortunately. With ZDF records it functions however. Even if I do not change the channel, but an admission show and these terminate, switch the VDR again on ZDF and the 1. Auido-Track is active. In the admission however the correct DD-Track. My Configuration: 3xTT-FF-1.5 / linuxtv-dvb-1.1.1 + test_av-1.28 + FW-2622 / vdr-1.3.37 Thomas
