I don't know what has happened to the playback of .mt2s files in 1.6.0, but

using FFmpeg transcode (WHS v1 with LAV codecs 0.51.3)
for output to a PS3 (1Gb network)
using lossless transcode settings

I get severe stuttering,
high bandwidth (as reported on the PS3 - scenes which were typically rendered at 60Mbs are now showing 200 Mb/s),
and forced LPCM stereo sound (as opposed to dolby digital 5.1).

The other Transcode engines are similarly affected.

As such I have gone back to 1.5.2 which is 'excellent'.
Note I used the same UMS and Codec configurations for both 1.5.2 and 1.6.0.

Thanks for making the topic. If possible, please post debug logs for both versions so I can see the difference

Apologies for the delayed response.
I have included logs for 1.6.0 and 1.5.2
On the 1.6.0 audio is Linerar PCM 2ch and PS3 rate averages 90mbs
On the 1.5.2 audio is Dolby Digital 5.1 and PS3 rate averages 60mbs

After looking through the debug logs it seems that this is all normal and expected behaviour; in 1.6.0 we added DTS support to FFmpeg which is why you get that instead of AC-3 like before. You can disable that in the "Common Transcode Settings" section of the "Transcoding Settings" tab.
Next we fixed a bug that made FFmpeg parse the "MPEG-2 options" value badly, which caused it to always use "vqmin=2" even when the user had specified "vqmin=1" for example.

So to clarify, the extra bandwidth is due to the DTS audio and the higher quality FFmpeg output. To go back to the previous behaviour you can disable "Keep DTS tracks" and change vqmin to 2 in MPEG-2 options (which is recommended anyway)

Thanks again
Yes, everything is now back to normal
The PS3 shows Liner PCM 2 channel; the receiver DTS 5.1 as input
I am now running with 1.6.0 !!!

Great, thanks for confirming
