I have 2 issues so far with my Playon DVR HD as follows:

1. I have no sound signal at all from the Coax digital audio out connector. The R/L connectors work but then I have no proper surround sound.

2. When viewing AV/in from a cable box anything above 576P resolution drops back to 4:3 format even though everything is set to 16:9. This is very anoying becsuse it means you need to switch video mode every time you switch back and forth between AV/in and other sources.

Both issues have occurred with both r3120 and r3420 version of the firmware. Amp is Pioneer VSX714, TV is Panasonic 106CM Plasma. Connection is Component video. (Amp has no HDMI!)

Any help with these issues would be appreciated. Thanks.

For point number 2, please note that the A/V input is only in SD...
So technically anything above 576p is not possible...

But some SD program is actually in 16:9 aspect ratio. Therefore, we should allow playing SD program in 16:9. My current workaround is to manual switch the playon!DVR HD to 570p mode. Then, it will output full width to my TV.
