Philips 722 (712?) - ff & rw work!

[borndevil]

Hi.
I decided to register my account just 4 answer to problems about ff & rw on Philips DVD players.
I have a 722, and after 2 months of work, finally I did it!

I seen that VCDs on my player work well.
After trying so many times I tried to use my brain (incredible).
I thought "What's the difference?"
"Yes, one is a VCD and it works, the second is a SVCD. It's different!"
"But what's the difference?"
I realized that with VCD, display says: PCB ON at the start.
And time lenght isn't displayed.
If I turn off PCB, I can see time and I can ff...
Uhm...
I tried so many ways to create SVCDs but I've seen that SVCD>40min show always a time of 32min and ff/rw fly away.
The conclusion is that VCDs use CBR and the player could calculate the lenght of video in the right way.
Using VBR the player shows wrong time: can't calculate the ratio beetwen file size & bitrate.
Try to use BBMpeg in CBR mode and default bitrate: the lenght of video is correct!
Now we want to use VBR, of course.
So way we want time displayed if it's wrong?
We can live without it and have ff/rw work.

Try to use DVD2SVCD.
Use I-Author 4 authoring and select chapters every 300 secs.
Put a title pic in every CD.
In settings of BBMpeg you must disable the second flag (2 secs) if U don't want to see an error in multiplexing.
Disable also the option for min bitrate.
Be sure to use the patch for CRC errors in CCE SP 2.5 if you use multiple Vpass (and you must use it).

Results:
Two audio tracks that work perfectly.
PCB is ON just like VCDs.
Now you can ff/rw and pressing >| |< you jump over chapters.
If you disable PCB in menu settings, video will not play properly.

The only thing don't work is subtitles.
I know there's a way to have them, the player have "karaoke" option too.
I'd like to try Philips SVCD package, but Philips removed it in licences site.

I hope this help.
Sorry 4 my bad english, I'm performing new test, I'll post result.
If you know how have subtitles please reply.
I thing it's essential with 2 audio streams.

Good luck!

If you are right, it seems that somehow you have made it. If so, you can help me and many others who are trying to find a workaround about the same problem.

However I am skeptical about what you've posted so far for the following reasons:

You say that used CBR.

So have I in all my projects so far (never VBR), both for video and audio. Yet, FF/REW never worked over 40 minutes.

You used I-Author. I've never managed to understand this awful piece of software. All the times I tried to do something with it, it always exited with a cryptic error message without any way to make me understand what I did wrong. Since then, I've made more than 30 fully functional SVCDs with TSCV.

Also read the posts in the relevant thread that I've started (40 min+ SVCD - No REW/FF on Philips DVD 712).

To conclude:

What is the solution?

To turn off PCB?

fyi, I-Author style subtiles won't work... since they aren't real SVCD subtitles...

it's a little detail I learned only few days ago;
I-Author creates CVD style subs, which are much like DVD subs; that's why they work on many DVD players, as it doesn't require big changes in firmware...

since philips players are one of the few players really adhering to the philips SVCD specs, they don't support the I-Author style subs, but only the real SVCD subs; which are very rare to find...

So...

- CBR seems to be the only way for Philips player to recognize the right lenght of the video stream.
But the value of CBR must be about 2200, it seems that Philips has taken this value as default for the calcule.
If you use BBMpeg in CBR mode at about 2200 you can see the right time displayed. I think it's the reason for having in VCD the right time: bitrate is standard and player know how calculate it.

- I think PCB is activated introducing chapters. In this 1st step we can already skip trough chapters but we haven't yet ff & rw.

- I really did it. I had about 80 mins of video, chapters, 2 audio strems and ff/rw working.
I'll look for settings I used in DVD2SVCD. Things I remember are:
* No flag in BBmpeg options where we must enter seconds for 2nd CD.
* Chapters every 300secs.
I repeat I did it, so we have a point of start for new tests, I'm sure the player works, it's just the way of making SVCD it's wrong (Philips said me that the player plays well original SVCD).

- For subtitles is there a solution to have Philips compliand subtitled SVCD? If someone knows...

- I'm trying other options for discover what I've used, I'll start to post here settings and results of my tests, if someone use other settings and find something, please post here.

Hey borndevil,

What are your findings so far? Have you been able to make another 45+ minute SVCD which does FF/RW on a Philips player and has a correct time-display?

Using CBR has not solved it for me (tried this a while ago). Please report your progress.
