Hi, I'm trying to understand what these commands? mean. Tried looking for the answers online, without a lot of success - especially as I'm not sure how to classify them. Here are a couple of examples. (the goto part is obvious) (Pre-Commands)
if (R[6] == 1) goto line 5
if (R[5] == 1) goto line 7
if (R[12] != 0) goto line 7
audio = 0 (track 0) (this sets the audio track I figure)
(Post Commands)
R[7] = 0
Call VMG PGC 3 (resume cell 1) (I think this stating to play the logo again)
The help file shows the list of functions? =, <, etc, but not an explanation of what a line like this does. What is "R" for instance. I'm sure these tell the player? what to do if certain conditions exist, but without knowing what they mean makes it difficult. Is there a link that explains these?
My test disc is a movie containing two versions - SE and TR. Currently I have set-up the title to start on a menu offering the version choice. Click either version button and that version plays. Was reasonably easy with the s/ware after some trial and error. Now I have the following issues.
There are a lot of "Pre" and 2xPost commands still remaining on each version title. Do I need them (difficult to know without knowing what they mean)? I try to follow with a player, but doesn't always help.
Then...when you stop the movie part way through, then hit play again, (Usually) the movie starts from the last point in the title. In my case, the root menu comes up. You can't resume the film from here (AFAIK). Pressing play starts the selected title from the beginning again.
I'm assuming a command makes the title start playing again from last point? How is this achieved? Should one just press the play button (while back at the root menu), or does a button have to be setup to "Resume Movie". If this is the case, how does this button know which version is playing?
I'm trying here (willing to learn), so please be gentle :D. Appreciate the help.
