Hi all,
Im somewhat familiar with DVDSP. Was wondering why the disks do not play on all DVD machines..only some..is it the bit rate??
Also why is the menu so pixalated? I can give all specifics to anyone who can help. Need to get this out to a client by Friday. Would also like it if someone wants to talk on the phone as well.

Possibly. If you could explain what is happening when the DVD "does not play". There are various factors that contribute to playablilty on some DVD players and not to others. More info is needed:
What encode settings did you use? CBR? VBR? Maximum video bit rate used is.......?
What program are you using to do the encode?
How long is this project?
Was the audio encoded to AC3 or are you using AIF audio?
What kind of DVDs are you using? Are they good quality?
[jared Kirshenbaum]"Also why is the menu so pixalated?"
What are you using to watch your encoded DVD? TV? Computer display? Pixelation problems with menus sometimes means it's been encoded twice.

Don

Two Pass VBR. Bit rate set to 6.4 and max rate to 7.5
What program are you using to do the encode?
DVD SP. went from FCP to compressor making a M2v with AC3
How long is this project?
All together since it is broken up between 12 seperate movies, it is about about 1/2 hour
What kind of DVDs are you using? Are they good quality?
DVD-R (Ativa) 16x/4.7 120min
What are you using to watch your encoded DVD
DVD players, PC's and Mac's... Some DVD players will play the disk, other DVD players will not.
Let me know if you need more information or if you would like to chat on the phone

Do the DVD menus look pixilated on a television or just on a computer display? If they're looking pixilated on a television it may be becuase you're using an LCD televsion to watch standard def interlaced footage. In that case your picture wil look its best being viewed on a tube type television.
You're doing it right by using Compressor to do your encode to MPEG2 and AC3. Since your project totals approx. a half hour you don't need to use VBR. Just use CBR Best with a constant video bit rate of around 6.5. A higher bit rate doesn't mean a higher quality encode. If your audio is a stereo file use the 192 bit rate for your .ac3 file. A VBR setting that spikes to 7.5 will cause some players to choke when combined with the audio bit rate. VBR settings are used when you need to get a lot of video onto a DVD at low overall bitrates. Lower bit rates won't cause player to choke using VBR.
Haven't heard of Ativa DVDs, although they may be okay. I always use Taiyo Yuden DVD-R discs which are considered to be the best of the best and I've never had a problem with them. Usually, anything that is made in Japan is considered to be safe. Avoid using knock-offs.
