Computers are set up to play all disc formats whether that be CD-R, CD-RW or what ever. Car stereos aren't. Some 'Will' play all, the flip side is that some will only play professionally burnt CD's. Having said that most will play CD-R's. Without further info I cant really expand on my answer but as I say it may just be inconpatibility.
Standard car sterios play CD's so a DVD of ANY type is not going to work!
IF it is a model that can play DVD's did you check to see if it can read DVD-R? ( Oh not of course you didn't) The other thing that can cause problems is the file format of the songs. MP3 is no good in a sterio that can only read WAV and vice versa.
Try READING the instructions next time!
videos and audios recorded on a computer are in a different format than what is read by car players and
dvd players. You need to convert videos to a format your dvd player can understand and audios also, unless
the audios are mp3 format. Those can be read on computers and devices
Unless your stereo says it's dvd compatible you need a cd.
U may need to convert the files to mpeg or something that ur car player may be compatible with or check if ur player can play DVDs. Check the manual man.
You shouldn't drive and watch movies at the same time, anyway.
