Yes, I will definitely look into the chainline. But the chain description I gave is weird. It's not that I'm certain that the chainline is off (yet, but it might be off a little just by looking at it with a naked eye), but it actually seems like the chain links don't all line up perfectly straight! It's like every few links, it looks like the chain is kind, well, crooked. If I turn the bike upside down and turn the crank, as I watch the chain travel, the links seem to be a little crooked.

My digital camera batteries just died, so I'm going to recharge them and I'll try to get a little video of it, if I can get close enough. Thanks.
