Different conf files are due to PMS is older build so new changes are not merged and rebuilt officially.
Missing divx line in one config is due to the bug in PMS/UMS code which I already mentioned in PMS forum but no officially released version includes it so better was to reencode all Avi files automatically(deleted line).viewtopic.php?f=6&t=15841&p=76201#p76099
About the tsMuxeR, this works without problems for me, including "keep ac3" checked. Never unchecked it.
About the bad AR(aspect ratio): when file is remuxed or transcoded, PanTv ignores AR. Only solution is adding special MEncoder params which transcodes video with automatically added black bars so AR is fixed.
PMS right now has a bug that custom mencoder settings on renderer level are ignored so it does not work in PMS right now. Bug mentioned here:https://github.com/ps3mediaserver/ps3me ... er/pull/98
We need to wait so bugs will be fixed and new versions released.
