Any general media compatability issues, if there were any, would be logged against the DRIVE brand and model.

Unless we know which maunufacturer and model of DRIVES are used in which production run of which e60s we can't begin to start a meaningful exercise (or use data that has already been gathered for specific drive models).

Remember DVD drive models are brought out every few weeks and it is credible that BMW source different DVD drive models at least a couple of times a year.

You COULD try this

and put in brand names (blank out the OPTODISC line) speeds etc you wish to investigate...

You may not have thought of this but your DVD WRITER is playing a role in all of this too...

aybeesea, I understood your point very well and I am trying to use this information at his best. But I was talking about probabilities of finding a type of disc I could buy with the help of others. You're saying my action is futile but I am willing to give it a try.

I understand OPTODISCOR8 is something I should avoid and OPTODISCR008 something I should try. But I am also looking to find other media types...

Interesting. My writer is Plextor PX-716UF external, on USB. How can I find out if this is at fault? I just bought for my friend a Samsung writer also external, but we never tried it yet.

Can you develop this idea?

Try the link above.

I did but it does not say which may be compatible best with BMW DVD slot.

Trying to capitalize on your knowledge, do you think I should try cleaning the lens in my slot with a brush disk? Or there is a possibility to damage anything?

aybeesea

Well you COULD try to write the SAME data onto the SAME brand of media with a DIFFERENT writer and play the data on the SAME drive you used before.

The conclusions would be pretty easy either way.

It is not an issue with compatability but the status of the laser on your drive. (having been in the IT industry for years I have seen this issue arise with normal PC/Laptop dvd-rom drives hundreds of times). A new BMW CCC system SHOULD read pretty much 99.9% of the brands, owever, knocks in transit of the parts (especally if the CCC has been removed from one car and later fitted in another) can lead to issues with reading. As all different manufacturers use slightly different materials and colours on the back of the DVD's, the index of refraction (the angle at which the laser bounces back) isnt always exactly the same. Even if out by hundredth's of a millimeter it can lead to problems with reading the disc.

You are more likely to get issues with "written" discs as opposed to "pressed" discs (ie. "manufactured" discs) as writable discs have a thicker protection layer on the surface, hence the angle at which the laser will reflect back at can change more.

Chances are if you put the disc you're having problems with into someone elses CCC unit, it will work fine.
If its really bugging you take it back to BMW if still under warranty, dunno how they'll react though.

Well, I am also in the IT industry but my opinion beg to differ. I thought the same as you until I had the same problems with my own disk in a brand new CCC equiped E90 330i my friend has bought. So, it should be something different.

good luck with a lense cleaner then....
