There is a new software update available for thiose using version 5.8.0 or lower. The new version is 5.13.0 and solves a couple of minor issues. The new software for the AVR250 solves a couple of problems one of which being the lack of output when playing a DTS soundtrack through a 5.1 channel system as was the case on the AVR300. The new version of software for the AVR250 is 2.90. Please note that although the problems and the machines seem similar the software for the AVR250 is not the same as that for the AVR300. I will add an update later, probably tomorrow when I have access to the full release notes so that you can be made aware of the fixes made.
