WDTV Live Gen 3, keeps rebooting itself while scrolling through videos

[christophiend]

I’ve only just bought one of these units and have the latest firmware on it (2.something?).  Having the same problems with re-booting, both while scrolling and after it’s played a couple of music tracks in a row.  Have tried rolling back to 1.7 firmware but still doing it.  Does anyone know of a good stable firmware I can roll back to to save me going through all of them?  Thanks!
