DVD writing gives incorrect data

[Bill Shannon]

I'm using VirtualBox 2.1.2 on Ubuntu 8.04. The guest OS is Windows XP with guest additions installed.

I'm trying to create a video DVD using Nero under Windows. I've got the host DVD drive mounted with passthrough.

I created a video DVD using Nero 9. I wrote the files to a folder so I ended up with a VIDEO_TS folder and all the files in it.

I used Nero Burning ROM to write those files to a video DVD.

I then read the files back off the DVD and compared with the original files on disk. In one of the large video files, I see two bytes that read back as zeroes every 65536 bytes.

If I use K3B under the host Linux system to write the same original DVD video files to a blank disk, and then read those files back, they're identical to the originals. That convinces me that the DVD drive and general DVD writing is working - it's not a hardware or Linux problem.
