I have had similar reading issues as a result of using low quality disks. And have worked around it by lowering the write speed to as low as possible. Have you tried with some good quality disks?
Recording/burning at 'max' speed is always buggier than burning at a slower speed. x52 vs x16, yeah, even if you were using the best media you could find on a fast computer (for the time) its still likely to be lower quality than a slower burnt disc.
You would see similar effect if you compared a DVD burnt at x20 to a x4 burn. That doesnt mean that a x4 burn is going to be dodgy at all.
BTW, the minimum burn speed is set by the drives firmware.
If I run liveCD of Ubuntu 8.04, it lets me write at 1x.
But I have to under-grade and install 8.04 just to get lower speed. nd definitely miss a lot from 10.04. The usb read/wrtie is better in 10.04. Well many other advantages.
First I couldnt resolve xorg issue in gnome, so I jumped to xfce (Problem 80% solved). Now I am having hard time by DVD-RW.
IOf your dvd reader can't read a x4 written dvd (by itself), it is no much use. Time to say goodbye.
Try cdrecord [other_crazy_options] -vvn speed=1 some.iso
That will give you a speed of 1 for the device and will simulate a write at the lowest speed, and will tell you in the verbose output what that speed is.
Hi bisiness_kid
All my work is fine with this dvd dev.
I fail to understand why I must go to get a new one.
All that needs to be done is cut down the write speed. The device is capable to do that.

When I write at lower speed say 1x/2x, all dvd roms read it easily.
The same recorder cannot itself read at 4x written dvd.
That's why I suggested looking to a replacement. Everyone agrees slower is better. But if your drive cannot read what it writes at 4x that's a basic functionality lacking.
