Maybe next generation media will be improved...

I think alot of the errors we see on today's DVD-R media is due to the fact that it's still early in the game...I remember early CD-Rs were prone to more errors than the later versions...As time goes on, I bet DVD-R media will be much better and will be less prone to any errors.

Yeah... Back when I first got a 2X CD burner for $450, I remember using those old "HP SureStore" CDR's that were $14 each for data I cared about. The regular dye ones were very poor quality at first, and good media was so expensive that people were glad to get the horrible stuff cheap. It's very similar to the current situation with DVD-R.

It seems that cheap DVD-R's have visible imperfections (speckles or wavy reflections) near the outer edge, and even better quality media is usually a shade lighter towards the outside edge. I've also noticed that when I re-rip a DVD-R, the read speed will go down to between 1X and 2X as it approaches sectors over 2,000,000 (the area beyond 4,100,000,000 bytes).

I've also noticed that everybody around here suggests using a max bitrate of 9800 kbps when encoding DVD's. Talk about asking for trouble! The DVD spec says 9800 kbps is the max bitrate for the whole stream, including all audio tracks and about 90 kbps of overhead! Pressed DVD's often have a peak bitrate of around 10,500 kbps, but the bitrate always drops to half that within a couple seconds, and it's much easier for a player to read a pressed DVD.

Even good DVD-R media will skip on cheap players sometimes. Combine a cheap player with cheap media, high bitrates, and completely full DVD-R's, and that's why you see so many people complaining.

Interesting read this thanks. it answered a few of my questions :o)
I have 2 dvd players one is a technics stereo which cost a small fortune and the other is a cheap usa import.
The stereo dvd player plays most of my dvd-r's fine but the cheapo jumps and sticks.
I take it this means different dvd players will play dvdr's different some will be more sticky and jumpy than others.
I laso reencode my dvd-rs to nearly the very maximum but i might lower it slightly to miss the last 10%to 15% to see if this helps any.
Thanks again.


I love this forum :)
