I currently only have two serious DVD annoyances:
Firstly, I hate it when they put hundreRAB of adverts and menus between you and the programmes on TV boxsets. Films I can understand - you will probably only watch them once every so often (once a week, month, etc), but with TV shows you often only want to watch two or maybe three episodes at once and I loathe having to go through the rigmoral of skipping adverts and navigating menus everytime I want to watch another episode!
Similarly, I will often watch a TV series on DVD every few weeks/months (rotating through them all) and have to see those same trailers and go through the same menu processes each time. I can understand the adverts on, perhaps, one of the disks - but for every single one in the boxset!?! Gah!
Secondly I hate the unskippable FACT piracy trailers. You wouldn't stand for a lecture on the dangers of not paying road tax from a cashier at the post office having just paid your premium, so why do I have to sit and be told repeadly that 'piracy is a crime' having just gone out and spent good money on a legal storebought copy!!! Of course, the ultimate irony is that those who *are* pirates don't have to sit through the patronising adverts 'cause they've had the good sense not to pay through the nose for an offical copy!!!
