Disable Warning on Seamless Layer Break

Recommended Posts

I'd like to be able to permanently disable the warning on seamless layer break

and preferably retain the seamless setting for all of my burns. It's the only way

I will ever burn a DL image, so I don't need the warning every time or having

to re-select it every time. Can you please allow it to be turned on permanently

and get rid of the warnings for seamless layer break? Thanks

It is a setting which should be on by default given its experimental nature (for most people who have not yet experimented).

Yes, it should default to non-seamless break and there should be a warning for

enabling seamless layer break. I just want to be able to burn seamless without

having to click it and accept the warning each time. Thanks.

 

Since I began using seamless layer break, I have never gone back to doing it

the normal way. Criterion and Superbit DVDs showed me that seamless break

works in most players. The rule against it is mostly obsolete.

I agree, but it seems to be out of spec. I also burnb DLs seamless. It's a very good feature.

Right, it's technically out-of-spec to have a seamless break, but certain

forms of copy protection are also out-of-spec. When it's done right, the

seamless LB should work in 95% of players.

 

It's like the rule against having only DTS audio for the movie. There is

no technical reason. It's just for compatibility, because you need a DTS

decoder. I've seen DVDs that only had DTS.

 

I use PGC Edit to set the seamless flag and remove any cell commands

before the LB. I've found that some players would have a pause on the

seamless break if there were cell commands before it. Getting rid of the

the commands increases player compatibility.

There is no technical reason re DTS, except the spec says you must have AN AC3 track somewhere on a DVD (at least in NTSC land) - usually a menu or a small extra will suffice. That rule is relaxed in PAL land.

 

I suspect it is more the influence of Dolby Labs over the DVD Forum than anything else. Nonetheless, I like to be in spec.

It doesn't have to be AC3. You can have PCM if you want. Every player supports

PCM, but DTS is less compatible for people just watching through a TV. I had not

heard that menus or extras would be adequate. I thought the movie had to have

Dolby or PCM audio to be fully compliant. That makes the rule almost irrelevant.

You could have Dolby menus and the movie in DTS only.

A lot of music DVDs only have PCM or PCM and DTS. If you have the compatible

equipment, you can author the disc however you want. The DVD spec has lots of

irrelevant and arbitrary rules, esp with regard to layer break. I have tested with

seamless breaks and even ECC block/VOBU boundary/NavPack. I've never had

a playback problem as long as the cell flags and commands were made seamless

with PGC Edit. The cell flags and commands are key.

Right. See http://www.dvddemystified.com/dvdfaq.html#3.6.2

 

However, it seems that this "rule" is a rule in name only as plenty of players will play DTS alone, as you have observed.

Discs containing 525/60 (NTSC) video must use PCM or Dolby Digital on at least one track. Discs containing 625/50 (PAL/SECAM) video must use PCM or MPEG audio or Dolby Digital on at least one track. Additional tracks may be in any format. A few first-generation players, such as those made by Matsushita, can't output MPEG-2 audio to external decoders.

 

The original DVD-Video spec required either MPEG audio or PCM on 625/50 (PAL) discs. There was a brief scuffle led by Philips when early discs came out with only two-channel MPEG and multichannel Dolby Digital, but the DVD Forum clarified in May of 1997 that only stereo MPEG audio was mandatory for 625/50 discs. In December 1997 the lack of MPEG-2 encoders (and decoders) was a big enough problem that the spec was revised to allow Dolby Digital audio tracks to be used on 625/50 discs without MPEG audio tracks.

It's really up to the programmers of the players as to how strictly they adhere to the DVD Specification. The standard is the standard - it is in the spec. It is not a rough "standard". If the standalone players choose to disregard that, so be it.

Well, the spec is the spec. It may not be standard (ie normal) but it is the specification.

It's a nice feature and my player will play seemless dvds. But I think about when this player breaks and I have to replace it. Will all new players play seamless?

Give me a crystal ball and I'll tell you.

 

Best to take a burned disk to the showroom and play it.

How about a Magic 8 Ball? :rolleyes:

 

The slight pause doesn't bother me hardly ever, though I would like it gone.

So I've just decided to keep the layer break just in case for future.

 

The thought of watching a movie and have it malfunction is much worse than a slight 1/2 second pause in a movie.

Well, we are all different. I despise the layer break pause. In the early days, most studios didn't give a shit about whether their customers got a decent experience from watching the DVD and put the LB anywhere - it was VERY noticeable. Today, things are a bit better, but it is still awful in many instances.
