Tested all night and as said earlier, by using 'loop mode' the A/V sync problem is solved. My problem still apply - DD/AC3 does not work! Reciever detects both DD2.0 and DD5.1 but as before there is no sound. I double checked by disconnecting SPDIF cable from DVB card to CMI8738 card to make sure the loop mode was 'active'. There must be something 'fishy' in my setup, or maybe my reciever will never work with this setup. ( Which is strange because it works very well with my standalone DVD player. ) @Werner: Any diagnostic test ideas? I might have missed if there is any tool in your plugin to natively send DD/AC3 from the CMI8738. I will search for an easy way to test what happens if I send DD/AC3 from CMI8738 to reciever. ( ie not a DVB/VDR stream. ) /Mel
