I hit this problem every now and then, I burn the DVD media with imgburn and it verifies fine
but is not recognized by any DVD player
however, I burn the same DVD media with Nero 6 (on the same machine minutes later) and it plays just fine on any DVD player
both using the same media, Sony 16x blanks
other computers see both burns fine
using a liteon iHAS121 IDE drive on windows 2000 SP4
any ideas on tracking down this issue?
