Philips 722/712 ffw/rw and subtitles report

[borndevil]

Well, seems that subs work!
I used new DVD2SVCD with Submux and I get switching subs!
That's cool!

Bad new is that I still can't fast forward-rewind but I notice one thing...
I tried to burn a SVCD 3:40min.
You know that if you burn a SVCD<40min ffw/rew work.
Well, It works.

Now, if I eject the 1st disk and without turn off player I insert a SVCD>40min, ffw works until time reach 3:40min!!
It seems player remember something of previous disk.
It's strange...

Any idea?

Yes, I've noticed that as well. Very strange behaviour. By the way, there's a guy on the vcdhelp-forum who has a DVD622 with the same ff/rw problem as us (I have a 712). However, he wrote that a friend of his bought a 622 a few days ago which does *not* have this problems (tested this with the same SVCD). Let's hope that Philips have actually solved this.

Do the subs work on a full disc too? Or did you try just an 3:40 minutes test disc? My DVD 622 freezes with disc over 40 minutes + selectable subtitles. So test with an SVCD disc that's over 40 minutes to see if plays all the way to the end. Only after that you'll know that SVCD subtitles work!

I didn't test the subtitles. I know they work on a short clip. At the moment, I really just want to ff/rw 40+ minutes SVCD's. I just hope Philips will solve this.

I have a philips DVD and have had similar problems with FF/Rew. I haven't solved the issue completely but I know that if you select close all GOPS and use BBmepg to mux then the disc plays fine. You can Pause/slow FF but not Slow Rev and not 4x/32x FF/Rev. But most importantly you can resume and jump to a particular time index no problems. However in my case the disc time doesn't display properly its about 2.5 seconds real time for every second displayed, but I think that this is a problem with the burning software and not the player.

I also confirm that I experienced the same problem with my Philips DVD 722 (firmware 2.9.6 010515 p29 5.1.14).

Test bench:
- DVD 'Toy Story'
- CCE 2.62
- VBR4 avg 2000 (min 300-max 2400)
- 1xAudio 160
- No sub
- Philips SVCD Authoring software (in order to maximise compliance with Philips hardware, hopefully).

Results:
- I made a CD with 50min13 of the encoded video:
--> Can't FF/FR
--> Chapters work
--> Time display at CD end is 39:39 (which is in fact ~ half of track size = 79min30)

- I made a CD with 30min13 of the same video:
--> FF/FR work
--> chapters work
--> Time display at CD end is 24:16 (also ~half of track size = 48min41 )

The player shows time as if the MPEG track was in fact played at CDx2 speed (ie. like it was encoded at max. bitrate 2600). So my feeling is that this wrong display problem is really a *bug* in the player. It is true however that depending on the authoring software used, the display doesn't show any time at all, just the dashes --:-- (for instance with VCDXBuild).

I confirm that subs work in a short video, I tried to encode yesterday with subs and player is frozen after some second of playing. I don't know if it's my mistake in encoding, some parameter wrong, 'cause video was too compressed (more than 2hours in one disk).

Let's say: if PBC is on, you can't see time, if it's off you can see time wrong. It seems that the player can't read the right time of video and try to calculate for himself, assuming max bitrate.

And when you ffw or rw, you can see that player jump to 10 mins, after to 20 mins and finally stops. It's because it reach the end of the disc!

It seems it really can't read the right time step-by-step, something about GOP sequence?

And in VCD it can calculate everything well 'cause the bitrate is fixed!

At this point:
Some bug in firmware (is it possible after all the problems like this in 711 ecc.?)... or we miss something...

uhmm.... uhmm....

We're not missing anything! I Read a post (probably on VCDHelp) that someone tested a commercial SVCD over 40 mins, and REW/FF didn't work with that disc either.

It is indeed a firmware problem.

As a matter of fact, Philips is installing a new firmware chip into my DVD712 right now. It is supposed to fix this SVCD FF/RW problem. I'll let you know when I get the player back if it has helped or not.

Sorry to kick this thread back up ;)
But i have the same problem with a friends Philips DVD711 dvdplayer.
The player freezes after a 30secs/or a few mins when the subs are turned on.

I understand (after reading some threads) that this is a firmware bug.
Does philips have firmwares online or something? Which you can burn to CD and flash by inserting it in the dvdplayer...
Or do you need to return your player to the store to have it fixed.

It depends on the model my 711 has rom, some has flash and can be
updated. Try yourself by downloading the firmware from philips
(I don't remember site search in google)
