  1. I've been troubleshooting for several days poor playback quality on MBC in WMC on my Xbox 360 extenders. I have LAV installed as my splitter, video and audio codec on my HTPC. I also have W7Tweaker set to use LAV Audio for mp4's vice microsoft. At first I thought it was due to unsupported container/codecs. So I ran all my files through handbrake. The movies in question are now: Container: mp4 Video: H.264, 4.0 profile, 1280x544 Audio: AAC, 2 channel All the above should play natively on the Xbox 360. I also have the Xbox 360 profile set under the DLNA portion of the MBS. It has mp4 with h264 and aac audio set for 'Direct Play' (see attached pic). I also have MBC to 'warn if transcoding' and I do NOT get a warning so I assume it is not transcoding. When I play the file through MBC in WMC on my HTPC it looks great! LAV splitter shows audio being played through LAV audio in the windows task bar. However, when I go to my Xbox and use it in extender mode and access MBC through the WMC interface and play the same file the video quality is horrible. Very blocky and poor quality, audio plays fine. The file should be direct playing on the Xbox, so why is the video quality so bad?
  2. Hi MB3-Community - The Good: Since it 'tis the season to be jolly I just want to say how happy I am that MKV (video & audio) and FLAC (audio) files are playing in Windows Media Center (WMC)/MB3-Classic on my HTPC and Extender for the first time ever thanks to installing Media Browser Theater (MBT)! The Bad: However, MP4 audio to accompany perfect MP4 video still evades me in 2013 on the Extender/MBC (see here). It has always worked fine on the HTPC. Does anyone have any suggestions for LAV settings for MP4 audio for the extender....please? What I Did: With a bit of time over the holidays I thought I would install the LAV filters based on the tutorial here. Unfortunately, the server that hosted the turtorial has not been able to restore it. So I decided to install MBT with the default LAV configuration as suggested. Needless to say I was surprised when it was the solution to MBC on my extender for so many items. Nice work dev team. If anyone has any suggestions that have not been covered in the topics below please feel free to join in. NOTE: When I attempt to check the codecs that are installed by clicking on the link in the Help>About screen in Windows Media Player 12 (WMP12), it just hangs and has to be killed. This is a new situation since installing MBT/LAV. See FAQ: How do I tell which codecs are installed on my computer? Example MP4 video/audio file with a dump of Mediainfo information. The audio is reported as AAC which is supported by my Extender.

  3. MBServer: Version 3.0.5083.27698 MBClassic: Version B12-4.1 MBTheater: Not installed PC Server OS: Windows 7 Home Premium 64-bit SP1 Codecs: Nothing other than installed with Win7 out of the box and MBServer Extender: HP MediaSmart Connect x280n Sorry if this is a bump of my own topic but could someone instruct me how I can go about troubleshooting mp4 audio playback failure on my extender? I am no expert on containers and codecs. From my standpoint, the mp4 files play video & audio in everything locally on my HTPC/laptop including Media Center and MB-Classic. Also, the mp4 files play video & audio with no problem on the extender in the native HP interface both from the local hard disk and network share from the same HPTC/Laptop (so the device can play the video/audio). It is just the playback through Media Center and MB-Classic that fails on the audio portion on the extender. Video works perfectly. ffprobe = Stream #0:1(eng): Audio: aac (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 124 kb/s (default) I would really appreciate a point in the right direction. I have not started installing codecs when I don't understand most of the settings and the files play fine locally outside of Media Center. Full clean logs are in the other topic. http://mediabrowser.tv/community/index.php?/topic/2583-extender-mbc-audio-in-mp4-container-not-playing/ Thanks, Tanamur
