I new version of PDVD8 (2521) released today 11 Feb, won't play ISOs mounted via VCD 5.4.2.3b. An unsupported drive message keeps poping up.
How was the image created (which program was used, version of the program, version of AnyDVD, is the image protected or not)?
Do you have latest AnyDVD running? If not, please try this.
I experienced the same problem after upgrading. I noticed that the BR logo (and DTS HD, etc.) were missing from the start screen after the update!
I then uninstalled PDVD8 completely, reinstalled it from the scratch and then applied the 2521 patch. Now it's working fine again!
Regards!
