Just got back yesterday with about 110 dvd's in my suitcase and no probs at all, either at Bangkok or Sydney airports. When I came back from Vietnam 2 years ago I did however have probs, but was at HCMC airport and not at Sydney. I think Ive worked it out tho - if you stack them all on top of each other in your suitcase, then the xray cant really tell how many of them there are. I made the mistake in Vietnam of stacking them all around my suitcase, so when they xrayed it, it prob looked like I had thousands of them!!!
