Just picked up a liteon 52x and I'm having an odd problem with audio discs...

I just picked up a rebaged Cendyne (liteon) 52x and the drive is amazing! But I'm having an annoying issue.

I bought some good quality TDK 48x certified cd-rs to go with the drive, and the safe disc picks them up as being 52x, woohoo I think. Well, I burn (through nero, or the built in cd burning in winXP) a selection of mp3s in audio cd format the way I always did before with my old burner, it burns, and it works in my computer. I put it into my car cd player, and it works as well, except that randomly it gives me a 'E20' error (can not focus correctly error.

I bring the cds in (I did multiple ones), and throw it through nero to do a cd quality check, and it gives me a perfectly straight green line showing the data burned flawlessly and the disc is perfect (I tested it in 3 different cd-roms with this test). I burn the next cd at 16x, and that one works perfectly in my car, on the same media. I check cd speed again and again it says it's burned exactly as correct at the first disc.

I've tried firmware updates and that didn't help either. Any ideas? I suppose I can just burn slower, but dang it, if the discs are supposedly perfect then whats the problem?

That's a common problem especially with car CD players. If I burn over 24x, my car sometimes won't read a CD until I reinsert it a few times.

Whats really bizarre is it seems to be at the siomilar track number that errors screw up, not at times. Like, track 5 is the most likely to screw up track with a can not focus error.

I've done some reading on teh net now, and this seems to be a common problem, cd freaks message board has said by multiple experianced users that the Liteon 48x and 52x (based off the exact same design, different firmware) are horrendous at making compatable audio cds. I pretty much had gotten this cd-rw drive because my originals that I was carrying in my car were getting scratched up and I heard that the DAE on the drive was fantastic, and it is... I managed to read some very scratched cds (albeit at a very slow read speed so I got no errors) without any data corruption or clicks... but it siappoints me that the faster speed audio discs have the TOC written kinda shoddily...

However, I did a search on cd freaks for compatability of data discs, and every says that those are top notch from liteon... maybe a firmware revision will fix this. does anyone here have this or the 48x drive who does audio discs that work at high scpeed? I'd be interested to know which media you use!

*EDIT* BTW, is the cd burning built into winXP based on a new engine, or does it use the same one as another existing program? I'm curious, as now I've read that there are issues with doing audio on liteons from nero, and some people say that they've used other programs and they work much better now... this is getting bizarre

Found the problem... apparently, there is a bug in any and all firmwares available for this drive where session at once (which nero uses by default) doesn't burn the toc quite right, which can cause errors on certain track changes. If I open another program and burn at disc at once, the disc works flawlessly in the car and my computer. I really hope this gets resolved as I love nero

Don't burn audio disc at 52x it's to fast for cd players.

A real cd is made by burning pits into the cd with high power laser, cd-r's are made by darkening area's that fool the cd player into thinking that there pits. If you burn at 52x then the laser doesn't spend as much time darkening the area so the cd player will have trouble reading it. Since cd burners burn slow at first and then speed up the first tracks may be ok but the middle and end may have trouble.

So burn slower so those dark areas are better quality.

For audio disc you should use the disc at ounce method and burn an entire disc of music. CD players will only recognize the first session. You can switch from the wizard mode to the advance mode to access all the settings.
