Can someone please tell me the latest firmware version on the PR-SC5508? I tried to update the firmware using the Net and getting a message that the NO Update. The unit was brought in mid Feb and showing the current version as 1051-0400-0310-2101. I having issues with the iPod/iPhone play using USB as it shuts down every 15-20 minutes. I did enough Google search and also called Onkyo but they could not help much or told they had no system to give me the latest version no.
