[K3B] Cant burn CD-R but works fine with DVD... cdrecord?
 
Cant get to burn any cd with it... Basically, I think its a permission error with cdrecord, but I dont know how to fix this. Each time I chmod it, it sets itself back with root only to execute. The only thing I can take to burn cd's is Gnome CD/DVD creator, and it doesnt burn audio cd, only data... I am using Suse 10.1. This is the error message it gives me when running k3b from a normal user

Anyone?? I am desperate and doesnt understand why I am the only one with this problem. I have a CLEAN install of Suse and didnt change anything yet...

Oh and BTW, I dont have ANY problem whatsoever when burning a DVD....

I see warnings, but no errors. Does the burn not continue? These messages are telling you that cdrecord wants to up it's priority so that it gets preferential scheduling over other tasks. This may be necessary since writing to CD's is time-sensitive. On a busy machine, cdrecord may not get the priority it needs for a good burn. This is a typical message for a non-root user.

Are you saying cdrecord stops after these messages? I would expect it to continue on and do the burn anyway. It's just a warning.

You're probably burning your DVD's using "growisofs", not "cdrecord". growisofs may not spit out this same warning, although it too is subject to time-sensitivity and process priority things.

Personally I've never had any problems burning as a normal user with normal process priorities. Despite the warning. But then, my desktop machine is not busy (typically 99% idle).

No it doesnt continue, it stops telling it failed with the following error... I tried to burn a cd loged in as root, and I had the same freaking result... Like I said, this is a STOCK, UNMODIFIED version of Suse 10.1.... I cant believe im the only one with this issue...
