Problems with DVDs

Okay, so, some DVDs I burn work and some don't and I don't get it.

I edit in Final Cut, export as a QT file, put in in Compressor, use default settings on DVD best quality 90 minutes, then toss those files into DVD studio pro and burn.

Now, the dvds always work on my DVD players. I have a Sony player, a Xbox 360, a Playstation 2. I also test DVDs out in my friend's DVD player, which came with a surround sound system for only $60.00 (it's terrible).

Anyway, I never have problems, but some festivals I send DVDs to call me and say they do not work in their players. Is there something I am doing wrong?

Should I bring the HD timeline into an SD timeline and go from there? I never had a problem like this with the DVX.

Thanks for the help.
 
could be lots of reasons. dvd+r and dvd-r are still different formats and not all dvd players play both. maybe try sending one of each format & see if that helps?

Well . . . it's more accurate to say that different players have more trouble with one or the other. But the compatibility rate for both is still over 90%.
 
You need to specify workflow:

1. Length of the video in total minutes;

2. Target and maximum bit rate;

3. Treatment of audio, ie AC3/Dolby 2 or aiff

4. Brand of blank media.

without this information and what set tops are not working, it's hard to suggest anything.
 
One video was 4 minutes long and the other was about 17 minutes.
The target bitrate was the standard in Compressor: 5 was the target and 7.5 was the max.
I used aiff audio
And the blank media was maxell.

After searching the forums a little, I figure I need to change the max bit rate to 6.5 and use Dolby 2. I probably need to buy better media, unless that isn't bad. I live in a fairly boring town with just the standard stores (Walmart, Office Max, etc) so is there better media I can buy from those?

Now I'm just trying how to do all this with a 92 minute video. I did a test with 83 minutes of the video (what I have done) and the video was 4.2 gigs on the dvd. That worries me when I'm going to add 9 more minutes.

Any suggestions on full length film burning?

Thanks for all the suggestions.
 
Putting really short videos on your DVD may be part of the problem. Older DVD players may not recognize disks that have less than 1GB of data on them, and some authoring tools such as those from Ulead have an option to pad the disks with extra data.

For maximum compatibility, I would
  • Use DVD+R or DVD+DL media with bitsetting to set the book type to DVD-ROM (if your DVD burner and software don't support this feature, use DVD-R media)
  • If you are forced to use double-layer disks, do not under any circumstances use DVD-DL media (compatibility is very poor)
  • Use high quality media (Taiyo Yuden for instance)
  • Keep the burning speed down (4x to 8x regardless of the media's rated speed)
  • Keep the total bitrate for audio and video under 8Mbps
  • Use closed GOPs
  • Pad the disk to at least 1GB if you have a short video
  • Do not use MPEG2 audio for NTSC disks (it is supported by most newer DVD players but is not part of the NTSC DVD spec)
I'm sure I've missed something, but these things immediately come to mind.

I wouldn't worry about putting another 9 minutes of video on the disk, use a bitrate calculator to find the optimum bitrate and adjust your Compressor project accordingly.
 
I would axe aiff audio.

Use Taiyo Yuden or Verbatim blanks. But them on line.

I get a better compatibility with -R, so THoff I disagree on that

Slowest burn speed you can burn at.

No paper labels.

Good one, I totally forgot about that! Don't use paper labels or something like a Brother P-Touch.

Even if a disk with paper label plays fine today doesn't mean that it will tomorrow. Heat from the DVD player or other sources will soften the glue and cause the label to shift, which causes a rotational imbalance and vibration. Too much of that, and you can't read the disk anymore.
