Found & removed wrong DVD structure! Whaqt does this mean on anydvd?



I just recorded a dvd with my jvc drm-100s standalone dvd recorder. i recorded something off of a cable channel. When i inserted the dvd, ANYdvd gave me this message:

Found & removed wrong DVD structure!

It also said this:
Media is a Data DVD.

Does this mean my dvd recorder doesnt make a correct dvd structure???

Also, what is anydvd doing to my dvd when it says it removed the wrong dvd structure, does it actually change the dvd-r that the show was recorded?
