1) What media are you using. ->Try TY.
2) What program are you using?
3) What type of CD compilation are you burning it as?
An Audio CD is different to a Data CD.
- Dropping some MP3's onto a Data CD compilation results a data cd with MP3's, which is not playable with a standard Audio CD player.
Dropping some MP3's onto an Audio CD compialtion results in an Audio CD, which should be playable by a standard Audio CD Player, if the CD's have a high enough reflectivity & a low error rate.
TY (Any) or MCC (DL+ only) CD's generally have low Error rates. MCC DL+ have a relatively low reflectivity & many players won't play these, especially car Audio players.
Crappy CD's (aka what you find in most stores, even with Big names like Verbatim, TDK, etc) will often have high error rates, or a large variability in quality, even on the same disc, let alone between discs in the same spindle, or different batches.
