So the hype, the excellent reviews and the awesome soundtrack convinced me to buy this game, despite my former experiences with RPGs. Now I get a disc read error on XC as well as Smash Bros.

I feel like busting the TV or something >

Seems it's double layer disc related? Other games I tried work fine.

Nintendo customer service is off drinking coffee till 13h (in two hours)... My Wii has been getting this error on Mario Kart Wii at the end of 2008 I think and was in repair because of that.

Anybody now if I can do something about it? Cleaner disc maybe?

Ask your next door elderly neighbours to let you loan their Wii until yours' fixed.

I've had trouble reading disks after over-working my Wii for too many hours. For example after leaving the disc for Other M (which is dual layer and cinematic heavy) in my Wii for too long, it suddenly stopped recognizing random games which were all single layer.

After unplugging the console and letting it cool off for a while this issue went away. I suggest you try the same. Also try cleaning the area around your Wii from dust, and also cleaning the vents and making sure they are clear. Another thing that might improve your Wii's life-span is disabling standby connection in Wii settings as the console tends to heat up when in that mode. A disc cleaner is also a good idea but you need to order one from Nintendo.

Thanks, I'll try that.

Also already arranged for a friend to lend me their Wii (not an elderly friend though)

So, your 12 years old friend :)

or their mom

Yup, it's safe to assume all Wii owners here are a child, an elderly or a mother.

It's also safe to assume most of them are horny children based on the posts :)

Yep Xenoblade is a dual-layer disc so your Wii's lens is probably dirty. You can try some canned air or Nintendo's official lens cleaning equipment.

Well, and me, I'm neither... I don't consider myself elderly yet

If its just dual-layer related, cleaning kits can be bought
