I can burn DVD-R, DVD-RW, CD-R (Audio) just fine using the Pioneer DVR-104/A04 using Nero (latest as of 8/20/02). However, when I try to back up large files (650mb) to CD-R in data format, the burn process goes through fine, but when I try to read the file back to HD, I get CRC errors. What could be causing this? The drive? CD-R media? I've tried reading back on various computers with different CD-ROM drives and even in the DVR-104 itself, but the same CRC error comes up.
