I have an "ASUS DRW-24B1ST c" DVD/CD burner running on XPpro with 4 g's of RAM. I tried to burn a DVD today and am getting an error message that the drivers are missing to burn the DVD. I don't recall there being an install CD/DVD that came with the drive when I installed it. SPECCY shows it as a DVD drive and is operating normal. It can read & burn CD's but can't read or burn DVD's. Any ideas?
