Hi all! Been using Xbmc on a Revo 1600 for the past month or so and absolutely love it! However, I've started encountering some issues with some of the MKV files I'm playing. I'll try and describe them as clearly as possible. I've spent the past few evenings scouring the forums, but couldn't find the exact issues I've been having, but I apologize in advance if I missed something obvious!
First off, these issues only affect standard definition MKVs. All my Bluray rips play fine.
Issue 1: When I start playing an MKV file, it plays for about 5 seconds, and then blacks out for 3 or so seconds (along with the sound), and then re-appears. At this point, if I have Interlaced handling set to 'Auto select', the movie is extremely jerky and completely unwatchable (setting Interlaced handling to 'none' seems to clear this issue up, except there are some files that clearly need to be set on Auto or De-interlaced).
Issue 2: This one seems to vary from file to file, but on most standard definition MKVs the audio goes way out of sync. One some movies (e.g. Resident Evil), the audio seems to only slip at the beginning of a chapter (going back one chapter and then forward again to the current chapter seems to fix this, although this is rather unpleasant to do throughout the entire movie!). The second variation sees the audio gradually slipping randomly, and the third (most extreme) occurs randomly with the audio slipping by about 13 seconds, and skipping forward/backwards between chapters doesn't fix it.
All of these files are being streamed via a wired gigabit network from a machine running Windows XP to the Revo (not sure if this has a gigabit port on it or not?). All files play fine via VLC on any other machine. Each file displays the exact same behavior each time it is played. I've included the MKV info for the worst scenario of audio de-synchronization in case it helps (sorry the formatting is a bit off):
With this file, the 'blackout' (issue #1) occurs about 45 seconds in, and then at 2:24 the audio 'jumps' forward by about 13 seconds, and the movie looks terrible (sorry for the improper terminology, but it get's 'line-y', like it needs de-interlaced, but setting the interlaced option to auto or de-interlaced results in the movie being jerky). Again, issue #2 doesn't occur on all standard def MKVs (although issue #1 always does). Case in point, Season 1 of Bones, ripped to MKV with the exact same program (MakeMKV) has no audio sync issues.
I saw elsewhere that someone had a similar issue (the less severe form of issue #2), and resolved it by updating to the latest version of Xbmc. I tried that, and my current version is: xbmc 9.11 R26018 (Compiled: Aug 19 2010)
Any thoughts or suggestions? I am more than willing to provide any additional details y'all might need! Thanks for your assistance!
