since I have updated the firmware of my QNAP TS-210 NAS, I couldn't watch any avi-Files on my Sony KDL-40EX725. In the new QNAP firmware (ver. 3.5.2) is Twonky 6.x included.
I have restored the QNAP firmware to version 3.5.1. It includes the Twonky version 5.1.6 - there are no problems to watch any avi-files.
What has changed in the new version? Please revise the twonky-version again to correct this problems.
