Okay, I’ve made a first stab at a jacket picture. I haven’t tried Nero yet, I just used the TMPGEnc trial, since you provided steps for using it . I created all three files from a JPEG of the movie cover, following your steps exactly, and placed them in the JACKET_P folder of the movie, then burned and played on my Sony standalone. Here’s what happend:
When stopped, the player displays something other than its own logo screen. Good first step, as it shows the player is recognising the JACKET_P folder and its contents. That’s where the good news ends. What it displays, seems to be a strange version of whatever was the last scene playing in the movie when the stop button was pressed, but in weird colours and outlines. Sort of like a colour negative, but not quite.
So, it seems as though the player recognises that there is a jacket picture which it should be playing. But what it actually displays is some distorted version of the last image it was showing before being stopped–as though that image was still in the buffer. I’ve been doing a lot of googling for jacket pictures, and it seems that a lot of people are having this exact problem, but for others it seems to work fine.
I haven’t found the answer yet, but it’s as though the jacket pictures are not in quite the right format or something. As mentioned, I made mine from a JPEG. Would it be better to use an MPEG still? On the other hand, isn’t that what we’re trying to produce in the first place? Any ideas?
EDIT: By the way, when I view the three images I made, in Windows Media Player, it displays all three just fine. But each is displayed at the top of a larger black window, so there is a large black border on the left, right, and bottom of the picture. Does that say anything?
