I've heard of a flame or a soldering iron working well). Our team used the round belt for 2012. We machined pulleys out of ABS to make sure that the belt wouldn't move. Many other teams have similar or the same way of keeping it in place. I've also heard good things about flat belt from teams like 341. Apparently if you wrap your shafts in electrical tape where you want your belts to stay the belts will actually walk back to their places if they get moved.
You can also get small metal pieces that are inserted into each end of the cord to hold it in a loop
