Is there a way to fool dvd player last memory?

[Talayero]

Hi,

I authored a dvd with a menu that has two audio streams. I wrote some commands to make that once you have entered the film and go back to menu the audio two is played.

In short, when i put the dvd in my standalone for the first time menu plays audio 1, when I go to the film and play menu again, this time is the audio 2 which is played.

The problem is my Pioneer 470 seems to have the memory of an elephant. I press stop button, I switch it off, I eject the tray, no matter what I do the player starts always at last memory point, that's to say with the menu playing audio 2.

I tried the dvd in two other standalones (Samsung, Kiss) and have no problem at all to start a fresh play after switching the player off.
I think my Pioneer has memory for five differents dvds, so one solution is to put five discs for the player to lose its memory.

Anyway, I appreciate some information about this issue.

How does players last memory work?
Is there a command I could write to avoid this last memory isue?

I thought about writing some precommand in the video manager first play, but it's obvious that players last memory doesn't care about first play.

Thanks in advance.

You could simply use the "Audio" (or "Language") button on your remote control, couldn't you?

You are right. It's only that I would like to set the dvd navigation for this to do the thing automatically.

As a matter of fact this dvd is a present for a friend and I'd like to surprise her with this two special audios in menu. The thing is now I'm wondering if she has a Pioneer too.

Anyway I'd like to be able to do a dvd that obeys always the commands, whatever the player you use.

While the player can remember what it was playing last I doubt it keeps all the register contents. In fact, that would violate the spec which states that all gprm's should be reset when a disk is inserted. So use a gprm to determine if the DVD has been played yet or not.

Thanks for answering.

I've just added some commands and found a solution.

These are the commands I used in the dvd that worked fine in Samsung and Kiss, but not in Pioneer:

Precommands Menu:
1.- If gprm 0 = 0 break
2.- Set audio track 2

Precommand Movie:
1.- Set gprm 0 =1

These are the commands that now make Pioneer work as I want.

Precommands Menu:
1.- If gprm 0 = 0 go to line 4
2.- Set audio track 1
3.- Break
4.- Set audio track 2

Precommand Movie:
1.- Set gprm 0 =1

I don't know why, but for Pioneer I had to order menu to choose the audio 1. I thought that if you say nothing player always choose first audio. That's what Pioneer did the first time you put the dvd in, but not the second one. Weird. Now it works.

Anyway If you know a better way (some different commands) to get the same navigation I get now, I would appreciate the information. I always write the commands intuitively and I'm eager to learn more.

I'm just curious to know if the DVD burned with these new commands also works properly on your other players?

[Talayero]

Yes. it works on the other players.

Sounds like your Pioneer is as picky as a couple of my SONYs.

Come to think of it, if you have access to a SONY standalone, I wonder if your original, "Pioneer-problematic" DVD would exhibit the same problem if played on a SONY...

I've had this problem with the same player. try this for fun! Play your disc, eject it, put another disc in, eject it, put the original disc in and with me it resumes where it left off from! :scared:

The only way I could get it to reset the disc was to press the stop button twice!

Cheers,

Pioneer DV-470 has a resume function for the last five discs
Manual page 18

Resume and Last Memory

When you stop playback of a disc,
RESUME is shown in the display indicating that you can
resume playback again from that point.
If the disc tray is not opened, the next time you
start playback the display shows
RESUME
and playback resumes from the resume point. (If
you want to clear the resume point, press
(stop) while RESUME is displayed.)
With DVDs and Video CD/ Super VCDs, if you
take the disc out of the player after stopping
playback, the last play position is stored in
memory. If the next disc you load is the same
one, the display shows LAST MEM and
playback will resume. For DVD-Video discs
(except VR mode DVD-RW), the player stores
the play position of the last five discs. When
one of these discs is next loaded, you can
resume playback.

Sorry, bought the player and threw the manual away straight away! :D

Well, it seems that the commands I added have something to do with the right behaviour of my dvd on Pioneer player. To explain why this is so you have to be an expert on dvd commands and unfortunately I'm not. The thing is with the first navigation I wrote the player didn't clear resume "pressing stop while resume is displayed", as the manual says, and with the second navigation it worked fine.

Anyway, I think that the first commands I wrote were enough for any player to follow them properly. But who knows, may be not, or may be it's only a Pioneer issue or a firmware issue.
