Same here. DVD+R fail for me at a similar rate, though DVD-R from the same brand are doing just fine. What's puzzling is that growisofs doesn't always notice errors while burning. Approx 1/3rd of errors are first detected while reading the DVD+R back in (MEDIUM ERROR READ BIG etc..). OTOH, I'm adding and later checking md5 checksums for every file; and I've never had a checksum mismatch. If something goes wrong, it's the whole reading of a sector or a bunch of sectors. Oh, and this happens with multiple DVD writers on different machines.
