Do you check your bootlegs for errors?

[rarnom]

I realized that I had created a sort of ritual everytime I get a new order of HK dvds. I sit down, look at each disc carefully under light, and then pop it in and make sure it loads properly (I eject it and retry it about 3 times to make sure) and then I fast scan through the whole disc because that usually can find any skips or messy spots. Does anyone else have an 'error checking ritual' that they do when they get a new batch of HK anime dvds?

How do the rest of you check your dvd's for playability issues?
