Burning DVD-video, only 35 minutes is ok

pingu · 06-02-2005, 06:44 AM

I have a movie prepared for DVD, structure is ok with all files correct.
The DVD-movie consists of 3 .mpg movies in dvd-pal format, length is 30 min, 10min, 10 min.
The initial three .mpg-movies play fine, the three VTS_01_#.VOB also plays fine.
Now I burn it using k3b or 'dvdrecord' or 'growisofs' or 'mkisofs' followed by 'cdrecord'
Same result: 35 minutes plays ok, then sound starts stuttering followed by movie stuttering, strange colored squares appear, more and more of this and finally movie stops about 11 minutes before end.
I made a new movie, this time with only the last two movies. The disc played just fine.
So it's a burning-problem, can't burn more than 35 minutes.
I tried changing speed, normally burns at 4x, but gets
:-( Failed to change write speed: 2770->3324 (tried 1x 2x 3x) or dvdrecord simply ignores the -speed
In k3b I chose "ignore" for speed, now it burned in 2x, but same problem. I bought a new IDE-cable but no change, hdparm reports udma2. Computer is P4 2.4GHz, 512 RAM, LormaLinux

And maybe I should add: I'm using a DVD+RW, but I tried once with a fresh DVD+R - same.

This can also be observered on some players if the bitrate of the movie is to high at some point.

Playing on PC does not know this limitaion, PC software handles these kind of "exceptions" way better.
Partly because of the fact that you have huge processing power on you pc, and only a small processer in the DVD player.

Hmmm... so I'll try to lower bitrate then...
But the disc doesn't play well in PC either, both mplayer and xine takes a very long time to open the dvd and won't play any better than dvd-player.

Now I switched to Debian (same computer), open disc with Totem. Same thing, error message is:

Code:

An error occured
The source seems encrypted, and can't be read. 
Are you trying to play an encrypted DVD without libdvdcss?

Is a movie encrypted when it's longer than half-an hour? If so, when is that done - by dvdauthor, k3b, dvdrecord or what? Getting 'libdvdcss' is not a solution since I want it to play in stand-alone player, I have to get rid of encryption (if the message is correct).

I dont think the message is correct.
Does mplayer say anything abnormal if you try to play the mpeg file from harddisk?
Can mplayer play the VOB from harddisk?
What are the exact error messages?

How exactly did you encode the movie?
(Did you encode the movie in the correct size/aspect ratio, framerate?)

I need more info to do beter guesses.

Before trying to play from a standalone player or burn a dvd, the file should be absolutely correct while playing on PC from harddisk.

The initial three .mpg-movies play fine, the three VTS_01_#.VOB also plays fine.
It also plays as dvd with
#xine dvd://usr/local/film/dvd/VIDEO_TS/
I created an image which I can mount and the movies plays just fine.
When I burn the image to dvd - using dvdrecord or k3b - it doesn't work. So the movie in itself is fine, there's something weird happening when I burn it? And as I mentioned, I use a DVD+RW, but also tried once with DVD+R no difference.

Opening the dvd-disc in mplayer, I get no error message at all. Mplayer just stops, tries to read from disc but obviously can't.

The movie is created in a few different ways:
Using tovid, transcode and Studio8 - they all give me movies playable from harddisk, but same error when burnt.
