Since our last caller couldn't be bothered to mention HOW he gets it to work perfectly, I'll explain.
Whenever you change a setting on the Render to Texture modifier, the Texure channel will revert to 3. ARRRRGHHHH!!!! WHY!!!????? Sorry, primal scream over.
So when you're done changing settings, make sure you set the Texture Channel or UV Channel back to 1 again. Then everything should be fine. If you're still having problems, save the UV's from the right panel beneath the stack once the Unwrap UVW modifier has been automatically applied.
Then if anything goes wrong, you can apply a UVW Unwrap modifier to your object, select channel 1 and Load the uv coordinates you saved earlier.
