I'm afraid that’s not totally true

. DVD does include an error correction protocol, but if your DVD player has too many errors to correct (caused by not ideal burning speed, or anything else), it will lead to a performance drop. If your player’s laser is not very well tuned, this performance drop can get so high that it can cause read errors and skips.

Also Data/Audio CDs that are burn in Mode1 (with error correction embed) will suffer with the same problem that I described above; and the ideal record speed is almost never the slowest or the fastest your recorder can get.

Well, it will not affect the video quality directly, but the playback quality. I mean, a media with fewer errors to be corrected will be more “light” to the player play, and less suggested to errors. It is a bit hard to find the best/ideal “burn speed”, because it will vary from recorder to recorder, and even worst, it will vary from media brand too. With audio CDs there are some tools that will identify and count C2 errors (correctable errors), so you can make tests and choose the speed that will produce fewer errors. I don't know if there is such a tool for DVD media. But as I already said, this ideal speed will be very
unlikely the slowest or the fastest your recorder can get.
