Some mp3 songs won't play?

[flobadob]

I made an mp3 cd to play in my car which is an astra. I put about 50 songs on it but for some reason a few of them won't play. The thing is when I play the cd on the computer they all work ok and also I played it on a dvd player and they all played ok but in the car 10 or so won't play and I cannot figure out why. Any ideas?

I really don't think knowing you have an astra was relevant here :)

They are encoded in a format your car player doesn't support. probably variable bit rate (VBR)

chuck's probably right

install this
http://www.nch.com.au/switch/mp3.html

add this to it
http://lame.sourceforge.net/download.php
then
look at properties of track that does play .... recode the ones that don't to match

failing that ... have you topped up the oil?

Just a shot in the dark are they all in MP3 format?

Cheers guys, that Switch program seemed to sort it when I converted them to 128kbs but I'm still not sure what was wrong as every song seemed to have the same properties except for differing bit rates but I didn't see anything about VBR. Anywho, sorted, happy days, happy christmas, happy guy, thanks again.

Bitrates are the key to all players
mp3 is the format ... and needs a codec
but the bitrate is hardware so cheaper players only have one range and use a divider to decode it
so 128, 64, 32 etc could be the golden numbers...
40, 48 etc would need to be added

now you know which works.... you know
128 is a "vanilla" number - probably the most common
