[QUOTE="greath, post: 271535, member: 76199"] [b]MediaPortal Version[/b]: 0.2.3.0 [b]Windows Version[/b]: Win XP Professional SP2 [b]CPU Type[/b]: E6600 [b]Motherboard[/b]: X1250 [b]Sound Card[/b]: Club Theatron [b]h.264 Video Codec[/b]: Core AVC [b]TV - HTPC Connection[/b]: VGA Firstly, with my first post, let me thank you for a great piece of software. Now, onto the problem that I am having:-) When watching 1080p backups I get audio drops on the SPDIF link every couple of seconds. I've tried several things to get around the problem, and it can be done, but there is no one setup that I can then use for every video I play. So in the end I would like to know why it happens and it's driving me crazy:-) It also wouldn't be bad if it wasn't for the fact that Media Player Classic can play the files with no glitches or audio drop outs at all. I've tried several graphs in graphedit that all work, yet when configuring Mediaportal to use those same codecs for H264, Audio and Audio rendering the SPDIF dropout still happens. I've tried FFShow for H264 decoding and for audio, Core AVC with FFDshow and AC3 filter and MPA decoder, and Cyberlink with FFDShow, AC3 filter and MPA decoder. All have the same result. Another odd thing is that if I don't use SPDIF passthrough, but decode it in the PC, then pass it out as AC3 640 over SPDIF it works. Only in passthrough mode does it glitch. My suspicion is thread-priority within Mediaportal. Is there a way to boost the priority not of Mediaportal but of the threads for audio, or do they run at the same priority as Mediaportal, as it also happens if I boost the priority of Mediaportal. Any suggestions would be appreciated. Thanks in advance. [/QUOTE]
