[QUOTE="bart0190, post: 557291, member: 87381"] Hi, I have problems with AC3 streams of live TV and recorded TV (.ts files). The video is delayed. With mpeg audio track it is ok. The interesting thing is that I have around 0.5 seconds delay for channels such as Pro7, Sat1 (which is quite a lot) but only a very tiny (almost not recognizable) delay for ORF1, ORF1HD, ARD, ZDF. ORF2HD has more delay than ORF2. So different delays on different channels. With DVDs, xvid, (avi, mkv), HD content etc. it is perfectly synchronized when using AC3 audio. Could this have something to do with the codecs? I already tried with SAF 4.00 beta8 and beta22 with MPA codec and ffdshow codec and PDVD audio codec. I also already tried with and without RAM-disk. Does anyone have any idea what this is caused by? Is there a known bug in tsreader? br bart [b]MediaPortal Version[/b]: 1.0.2 [b]MediaPortal Skin[/b]: blue 3 wide [b]Windows Version[/b]: Windows XP SP3 [b]CPU Type[/b]: AMD Athlon X2 4850e, 2x 2.50GHz, boxed [b]HDD[/b]: Samsung SpinPoint F1 640GB, 16MB Cache, SATA II [b]Memory[/b]: 4 GB DDR2 PC2-6400U CL5 (DDR2-800) [b]Motherboard[/b]: Gigabyte GA-MA78GM-S2H (rev.1.0) [b]Video Card[/b]: ATI Radeon 3200 HD [b]Video Card Driver[/b]: ATI CCC 9.5 [b]Sound Card[/b]: onboard [b]Sound Card AC3[/b]: optical out SPDIF [b]1.
