    Thanks for this information, smitbret. We don't have any DirecTV devices here so we can only go on what our users tell us regarding file support and how Mezzmo is performing with these devices. Any information you can provide will certainly help.

    Mezzmo Android: Install it on your tablet, smartphone, Android TV or Amazon Fire to browse and stream files from your Mezzmo library to all your devices. Full details at http://www.conceiva.com/products/mez...mo_android.asp
    Mezzmo for Kodi Add-on: Install it into Kodi to stream files from your Mezzmo library directly in Kodi. Full details at http://www.mezzmo.com/wiki/doku.php?...odi_user_guide
    Mezzmo for Roku App: Install it onto your Roku to stream files from your Mezzmo library. Full details at http://www.mezzmo.com/wiki/doku.php?...oku_user_guide

    OK, so I took a clip from the Blu-Ray of Despicable Me and encoded it at different bitrates (5mbps-25mbps) in the MPEG-2 format. The encoding was done with Xilisoft Videconverter and the bitrates were constant, not variable. Audio was also encoded with MPEG-2 at 128k Stereo.

    I streamed it with the HR24 profile and turned the transcoder off. Errored out at 25k, 20k, 18k, 12k, 10k, 9.5k but played fine at 9k. Looks like the absolute peak to include the audio and video is 10k and it's probably only safe to encode in the 8k-9k range.

    Incidentally, I cleared the transcode files for 127 Hours again, set the quality for 720x480-Lowest Quality/Fastest Transcode, turned the transcoder back on and played it back. Same error, same spot. Found it odd that the TV did not upsample the picture to 1920x1080; the 720x480 picture was entirely windowbox/letterbox on all four sides... or did FFMPEG add the borders in the transcode? I wish I knew more about FFmpeg.

    I am having the same problem streaming to my Directv HR2x receivers (since upgrading to Mezzmo v3.0). The most annoying problem is some HD movies stop playing saying the bitrate is too high. I did NOT have this problem using V2.7. I would like to try fixing the problem the same way that smitbret did - by replacing the ffmpeg.exe file in the Mezzmo directory. Does Concevia use a custom version of ffmpeg or can I download the static Build directly from http://ffmpeg.org/download.html ? If I can use the ffmpeg.exe from http://ffmpeg.org/download.html and I am running Win7 x64 - which version should I download, x86 (32 bit) or x64?

    Thanks,

    We haven't gotten it fixed, yet. Changing the FFmpeg version solved the picture quality issue, but the HR24s keep dropping it due to bitrate. We are working on a resolution, though, but it will probably take time.

    Smitbret,

    Thanks.. I hope there is a fix soon for the bitrate issue.

    I have another (general) question. Since Mezzmo has no Device Profile for the Directv HR34 - which profile does it use when trans-coding? Streaming to my HR34 from Mezzmo is working for non-HD video - so Mezzmo must recognize that it needs to trans-code to mpeg2 somehow. Is there someplace in the app that I can see which profile is being used?

    Go to the Media Devices dialog in Mezzmo and you will see all your devices listed there. In addition, the device profile that is assigned to your device is listed there. You can change the device profile to whatever device profile you wish to use. For your HR34, choose one of the DirecTV device profiles. After changing the device profile, restart your Mezzmo server and try streaming again.

    Thanks Paul for the info, I have HR20, HR22, HR24 and HR34 receivers - all 4 are using the HR22 Profile - from a previous post that I read, it should not matter since all Directv HRxx receivers follow the same mpeg2 protocol.

    If you roll back to v2.7.1 it should work fine on all of the DirecTV boxes regardless of which profile you use. I know when the HR34 came out, there were some problems with the MediaShare function within the box itself but those issues have been resolved on a DirecTV level. I would imagine that any of the profiles would work with the upcoming HR44 as well.

    Please keep this post updated. I am also having this issue. I had to downgrade to 2.6.7 to make my mediashare work again.

    I started a thread on this before I read all the way through this thread. I'll watch for resolution here. In the meantime, I will roll back versions.
