Car CD player, DVD player vs computer CD reader
My computer CD/DVD player never skips/gets stuck playing a movie/CD,
while a dedicated DVD player routinely gets stuck and often goes into an infinite loop of track search. Same with the car CD player - it often can't start playing a certain CD or skips on the same place in a CD (so it's not bump-induced). The unability to start playing a CD in the car is "cured" by reinserting the CD over and over again, and eventually the car CD player starts. But if it starts skipping, the only "cure" is to go to the next track, it can never get out of a skip. Why is that? Do computer CD/DVD readers use more powerful/better focused laser diodes than car CD players/DVD players? Can I buy a car CD player which would be just as reliable as a computer CD reader? What spec should I look for? I pretty much gave up on the DVD player, I just play movies on a laptop. |

oups.com My computer CD/DVD player never skips/gets stuck playing a movie/CD, It is in good shape, or has the good fortune to play mostly discs in good shape. while a dedicated DVD player routinely gets stuck and often goes into an infinite loop of track search.

Do computer CD/DVD readers use more powerful/better focused laser diodes than car CD players/DVD players? I've seen certain of them do everything you're complaining about with the other players. Can I buy a car CD player which would be just as reliable as a computer CD reader? IME, most of them are. What spec should I look for? One that works well. I pretty much gave up on the DVD player, I just play movies on a laptop. Try cutting loose some cash - good DVD players aren't all that expensive. |

Car CD player, DVD player vs computer CD reader
I've had ~10 computers and none of them has ever skipped or was unable
to recongize a CD with normal wear and tear. I've had ~10 car CD players and home VD players and they consistenly recognized less CDs with normal war and tear. So, given this information, I can't buy the bad shape/good shape argument. I ripped all of my CDs and transfered the music onto an iPod. But I still have to play a CD the car occasionally |

Same with the DVD's, are they burnt or factory? |

I ripped all of my CDs and transfered the music onto an iPod. But I still have to play a CD the car occasionally The most common problem with car and other CD players is cleaning-related. Either dust or smoke residue has settled in on the objective lens or inside on the turning mirror, or the moving parts such as the gears, rails sliders, etc have their grease gummed up with dirt etc, or even hair or other debris impeding their movement. With DVD players, the problem is more often just a marginal or bad laser pickup. DVD players and drives are much less tolerant of a noisy or interrupted data flow than are audio cd players. The above applies to both computer drives and standalones. Mark Z. |

The usual cause of CD player problems is wear on the rails, crappy two dollar transports and poor lubrication. I've never seen an automotive CD player have any problem with a dirty lens. A "CD cleaning disk" is good for nothing but as a surefire way to trash a CD player's lens. |

A "CD cleaning disk" is good for nothing but as a surefire way to trash a CD player's lens. I'm sitting here in stunned disbelief. If you've never seen a dirty lens in of all things a car deck, then you are living a charmed existence in this regard. And rails do not for the most part "wear". They simply gum up from bad lube and debris. Agree on the uselessness of cleaning discs. Mark Z. |

But I still have to play a CD the car occasionally The simple reason that a computer drive can sometimes read disks that other drives can't, is that because a computer drive can read faster than real time, it can re-read tracks whilst the computer buffers the output, and you may not be aware there is a disk problem. Most home and car players cannot do this, and the result can be anything from clicks, stuttering to complete silence. I've never had a single problem in over 3 years with my car CD/MP3-disk player though MrT. |

Dumb question: do they make car CD players with a capacity of computer buffer? |

Well most good car CD players have *some* buffering to reduce skips on rough roads. The actual capabilities and performance depends on the model of course. I did hear a car CD player that had no buffering at all once. Brand new, and even on a smooth road with good factory disks, it was totally unlistenable due to skipping :-( MrT. |
