Welcome to the Forum.
In future when making CD Freaks Forum postings suggest providing the below minimal information so that Forum Members will be able provide meaningful assistance to you.
-> Provide the full Name(s) and Version Number(s) of the software program(s) you are using to processes your Commercial DVD Movie Title(s).
-> Provide the Error Code(s) and complete full exact Error Narrative(s) you receive when you experience your problem(s).
-> Provide the full Name and Region Code of the Commercial DVD Movie Title(s) you are experiencing your problem with.
Since you failed to state the version number of AnyDVD you are currently using suggest visiting SlySoft (http://www.slysoft.com) and download the newest current up to date version of AnyDVD.
Perchance when you experience your undefined â€œerrors on dvds now and thenâ€ problem suggest using the â€œAnyDVD Ripperâ€ function of the AnyDVD software program. To access the â€œAnyDVD Ripperâ€ function of AnyDVD with AnyDVD activated right click the Red Fox Icon located in the bottom right corner of the lower task bar and click on â€œRip Video To HardDiskâ€ and follow prompts. Quite possibly using the â€œAnyDVD Ripperâ€ might correct your undefined â€œerrors on dvds now and thenâ€ problem.
