Strange DVD

I recorded a movie using my TV-card and wrote it on a DVD-R (Lead Data 4x).
After it was written my DVD writer (Pioneer 106D) could not read the disc anymore, it was like there was no disc in the drive.
So I put the disc in my PS2 to try it out and it played without any problems. This means the movie is written like it should, so I don’t understand why my writer can’t read the disc anymore.

This was the first time I used a Lead Data DVD-R, I always used Princo’s before and never had any problem with them (which is also strange because I read that many people have problems with Princo DVD-R’s).

I used Nero to do the burning.
