does a dvd skip on certain players? and how does one submit to festivals when this horror is a possibility?


what prevents this skipping? my render is mpeg type 2 and to tell the truth, my DVD's have played on almost all players so far....except one, the other night. which got me thinking what if festivals have this player?


i use Sony dvd architect to author....is this the problem?
 
the only time I've really ever encountered skipping of my dvd's was when burning at higher speeds. If you aren't already, I might suggest burning your dvd at the lowest speed possible and see if that helps.

Also, sometimes choosing too high a bitrate can have an adverse effect on playback across a full range of dvd players... at least that has been my observation.

Later,
Jason
 
Maybe try to author with a couple differet programs to be safe, lower the bitrate on the backup?
 
I know some players weren't made to handle burned DVDs. Some were made specifically to not handle them. Could be related if the player in question is an older one.

Totally agree with Jason, I've found that cheap DVD players have trouble reading DVDs burned at high speeds. I burn single layer DVDs at 4x and double layers at 2x, always verifying the disks as well.

should I render at a lower rate as well?

No, burning the disk slower does not have any effect on the data, it just gives you a better chance of minimising errors on the physical surface of the disk. Think of it like a printer, if the page is printed quickly, it's likely that the accuracy of the print will be lower than if you printed it more slowly.

Rendering slowly will have absolutely no effect on your work.
 
Thanks

I am burning at 6500 bits. Before, i was burning at 8000.

I can now fit my entire time line onto one single layer disc, as well
 
yeah lesser players don't have the ability to sustain an 8kbit datarate. 6.5kbits should make all the difference you need.

I was not referring to the datarate of the encoded MPEG files for the DVD, I was talking about how fast the DVD spins in the drive while the laser burns the data on to the disk. What I was talking about does not make a difference to how much actual data is burned to the disk.

Most DVD players should be able to handle about 9.5 Mbit at least. Most mass produced DVDs have video at around that rate. If the players couldn't handle it then they wouldn't be able to play most mass produced DVDs. I think that the difference a lot of the time is that the mass produced DVDs are pressed from a mould extremely accurately and than data errors can occur if you burn them with a conventional DVD burner too quickly.

But good point, Zac, maybe the next time I'm having trouble with a cheap DVD player which won't play mass produced DVDs I'll burn a reduced data rate disk just to test it out.
