Big mistakes you made pursuing your Home Theater?

I think it's worthwhile to consider that despite our best intentions and research, we can all make mistakes trying to build the best home theater with the budget we have.

One time, years ago, I spent $300 on an S-Video cable to connect to my projector. It took a long time to realize how much I'd been swindled and now I'm overly cautious when buying cables.

Also, for years, I set my speakers to DTX: Virtual X, but only had a 5.1 setup. I thought the "loudness" was better, not knowing I was losing fidelity across the surrounds.
