[QUOTE="mm1352000, post: 768988, member: 82144"] [b]Re: ts stutters - after renaming to avi runs fine[/b] Hi bbathome Wow, 1.5 years is a long time to put up with such a problem. So let me clarify a few things for you first. When you play a file, MediaPortal uses a splitter to separate the audio, video and subtitle streams inside the file into individual streams. Those individual streams are then given to codecs so that the streams can be decoded, and finally the codecs pass the streams to renderers (which are basically the video card and sound card when you play a file). Now: why have two codec sections? Simple. Because MediaPortal uses one splitter (the MediaPortal TsReader) for splitting TS files, and another splitter (the system splitter, commonly Haali, Gabest, LAV...) for splitting anything else. The TsReader splitter is not compatible with many AAC codecs (because it doesn't support network abstraction layer unit decoding, also known as NALU), which is why you don't have the same options for that setting. Off the top of my head, I only know of 3 compatible AAC codecs: 1. Monogram 2. DivX 3. Mainconcept The system splitter will be compatible with many more AAC codecs - FFDShow, Microsoft, Cyberlink etc. So that means that either TsReader cannot properly split the file or the Monogram codec cannot decode the audio. As above: it is because the two splitters in use are not compatible with the same sets of codecs. For us to support the other codec requires [URL="http://mantis.team-mediaportal.com/view.php?id=2831"]this mantis issue[/URL] to be resolved. The work is difficult, and not many team members have the skills to do it. Further, those team members tend to be the most busy! Hopefully my explanations make sense to you. There are 3 options for you: 1. Rename the extensions. 2. Wait for the mantis issue to be solved. 3. A hack! :D I do not guarantee that this hack would work, but it is worth a try. What you need to do is manually edit your MediaPortal.xml configuration file (in any text editor like notepad) and enter the *exact* name of the codec that you want to use in the [B]aacaudiocodec[/B] setting under [B]mytv[/B]. For example, if you want to use the Microsoft codec, enter: As I said, no guarantee this would work. If it doesn't work, then there may be another problem with TsReader, and it would be helpful to have a sample. mm [/QUOTE]
