Last week I purchased a Yamaha CDR-R651 CD burner. I have been happily burning CDs from DVD, CD, vinyl, etc without issue on my system. I have successfully played my new CDs on my home CD changer and car CD changer without issue. However, a friend reported that he could not play a CD I made in his car. He said he gets a "weird" error message and the CD is spit back out. He was able to successfully play the CD at home. The Yamaha unit in question does use SCMS to identify first and second generation copies. The CD in question is a second generation copy. I have read on-line that some professional grade burners allow SCMS override, but this unit does not for digital to digital transfers. So here are my questions: (a) Is this a SCMS issue? (b) If not, could it be a media compatibility issue (I'm using Memorex Music CD-R discs that are stamped with the "Digital Audio Recordable" marking)? (c) Would this issue be resolved by upgrading to a professional burner? Thanks for any help/guidance you can provide. Life is too short to be dealing with issues like this.
