GigaRec CDs at 1.3X

I have recorded some Audio Cds with using Gigarec at 1.3X (maximum offered by my drive: PX-755SA) and I could play it in my car Stereo without a glitch or any problem. I could not play the same cd in my discman, or any other computer. Is it safe to play it in my car, evethough I dont have a problem. I know the bits are compressed to much but I like the idea to have a full concert music in one CD as example. :smiley:

Is the laser of my car stereo damaged by playing such discs? please Advise :rolleyes:

So far i’ve not heard of any negative effects on hardware caused by GigaRec.
