Storebought DVDs generally have copyguard built in.
You do have a “fair use” right to make your own backup copies of discs you bought, but not of ones you rent.
To do this, tho’, you need to have something that will defeat the copyguard.
A “filter” device between the player and the recorder is needed, or either the recorder or player need to be altered in some way.
There is a hack that worked with early versions of the 5005’s firmware, and would allow it to record copyguarded material.
This would not, I believe, allow it to PLAY a copyguarded disc into another device without the copyguard being an issue. (In other words, it’d record copyguarded material, but I don’t think it’d “filter” the copyguard signal out of a disc it was playing into another recorder.)
Maybe someone can correct me if I’m wrong.
If there’s a hack that will allow the 5045 to record a copyguarded disc, you could try it, but I don’t know if such a hack would work for the hard drive. It might work for the DVD recorder only.
