> First of all I want to take a moment to state how hilarious it is you used DVDShrink: a tool developed for copyright infringement of content. Yeah, the irony wasn't lost on any of us :]. > What you described is the standard authoring process that even I did back when it was fun to make home DVDs. One year after I left I heard from a coworker that they were going to close shop. Director had visited a freelance guy who was doing authoring with a single consumer PC box and he saw the writing on the wall. He wouldn't have been able to keep his team in-house with all the costs associated if distributors started authoring in-house or spread the orders among freelancers and drive prices down. So that studio left the market and went back to digital picture/movie effects. At that time, being a student, I also tried out adobe encore (I think it was the name) as an alternative the much expensive authoring tool (I think it was sonic but I am pretty sure there was another, both didn't look like a toy interface and the other one had a different name) and thought "wtf, it's way easier to author with that that almost doing assembler with the professional tool" but I found out it didn't produce 100% compliant DVD. Anyway. > But regarding unskippable content, it is difficult to prove if the code you described will be respected by all brands of players. I recall that JVC players would always go back to the main menu as soon you press STOP and it would then start the playback over when Play was presented. Pause is what would halt playback temporary. Its been a while since I used JVC players though. Ooooh. I think I understand your point now. Yeah, if the hardware indeed decide to ignore anything happening during an UOP block then nothing would work. My memory fails me, assuming the software can register keys during an UOP block even though the UOP logo blinks maybe what we did was register keys during the UOP block and disable the flag on the fly to give back user control (but then hw players that ignore anything while a UOP block is being played would result in non skipable content obviously) or maybe the combination had to be entered before so it sets a flag that is read before the next block to check if it should disables UOP on the next block (or skip it entirely and drop the user to the main menu ?). I am sorry to say I am unable to remember more details and I didn't keep in touch with anybody there :/.
