DVD Problem

[LoseThos]

My CD burning code works fine but my DVD burning does not play well with Windows. If I burn a DVD, it boots my operating system and is readible from my operating system, but Windows doesn't like it. If I use a MagicISO, burning windows utility, the ISO image file works on a DVD, so the data is not the problem. When you close-out a CD or DVD, you have to send codes and I think my codes for closing a DVD are not right. Anybody know about this?

Code: Select all

void ATAPIWriteBlks(LTBlkDev *bdev,U1 *buf, U8 blk, U8 cnt)

    U8 U4s_avail;
