EDIT: It's the vid playback issue I'm interested in, see my post above.
Can you try creating advancedsettings.xml with the following content:
XML
<?xml version="1.0" encoding="UTF-8"?>
<advancedsettings>
<network>
<buffermode>0</buffermode>
</network>
</advancedsettings>
Does this help?
It seems like there is a problem initializing the NAND.
Am I having a bad/unsupported NAND? How can a determine which NAND type I have?
Can you try tunning 7.0.1.2?
