Denon 1930 HDMI Problems - Please Help!

Hi guys,

Been reading the forums for a while now, but never actually signed up as I was certain I wouldn't actually be able to add anything that might actually help anyone!

I'm hoping someone out there might be able to give me some advice, I recently purchased the new Denon-1930 upscaler (which looks lovely and hasn't had any lip-sync issues by the way ). Have it hooked up to my Toshiba 46WM48 via HDMI, with the player set to 1080i (the optimum setting for the Tosh's HDMI, according the manual).

The first film we played was perfect (R1 of Cars), but all films after that the HDMI connection seems to momentarily give out every 5-25 minutes, flickers to blue screen, then comes back on (all different types of films, R1, R2, R0). I've tried switching the upscaler to different resolutions, switched every single setting on the players setup menu, etc. The connection is fine, albeit not as good, via Scart and Component.

I still have a few days to return the player before they charge me for picking it up, but obviously I'd rather not do this if it's just something I've overlooked or haven't tried yet, so I'm hoping someone on here can help me out... me and the Mrs. would be extremely grateful!

cheers!
