Hello Support, 1) DVD Region Mask: How to use DVD Region Mask Property in DiscInfo class of StarBurnX? Will you please kindly guide me & tell how to use it? Ex. For one of the Copy Protected DVD it is reported as 237, but what this means? 2) Is Disc Dual Layer: How to detect whether inserted DVD is Dual Layer or not? Ex. Now with the same DVD Disc Type is reported as 128 means DVD ROM. 3) Disc Contents: How to check Whether inserted DVD is Video DVD or Data DVD? So that this can be used in Grabber section to call proper API. |

Hello, 2) Dual layered DVD discs should be one: STARBURN_DISC_TYPE_DVD_PLUS_R_DL Media disc is Dual Layer DVD+R disc STARBURN_DISC_TYPE_DVDR_DL Media disc is Dual Layer DVD-R disc 3) Check that files system if ISO9660 ... the next you should check presence of the VIDEO_TS folder  Regards, Dmitry |

Hello Sir, I have one CSS Protected DVD with supported DVD Region 2 & 5. This information is taken from Nero InfoTool attached log file. Here value of discInfo.DVDRegionMask comes up as 237 Code: Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 1), "NONE", "Region 1")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 2), "NONE", "Region 2")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 3), "NONE", "Region 3")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 4), "NONE", "Region 4")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 5), "NONE", "Region 5")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 6), "NONE", "Region 6")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 7), "NONE", "Region 7")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 8), "NONE", "Region 8")) for these tests it is giving me only DVD Region 2 as output. I guess something is wrong from side. It should return me DVD Region 2 as well as DVD Region 5. Will you please kindly tell me, if anything wrong from my side.

Hello I guess you should interchange parameters "NONE" and "Region X" Regards, Dmitry |

Hello Dima Sir, First I tried that way only but no luck. I tried following: Code: Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 1), "Region 1", "NONE")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 2), "Region 2", "NONE")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 3), "Region 3", "NONE")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 4), "Region 4", "NONE")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 5), "Region 5", "NONE")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 6), "Region 6", "NONE")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 7), "Region 7", "NONE")) Console.WriteLine(IIf(CBool(discInfo.DVDRegionMask And 8), "Region 8", "NONE")) I got following answer: Region 1 NONE Region 3 Region 4 Region 5 Region 6 Region 7 Region 8 Hence I tried the another way mentioned in above post by swapping outputs, but no luck there also. This DVD supports DVD Region 2 & 5. But somehow getting And expression true for DVD Region 2 only. I understood what Anton Sir told. So is it the case, that I have to convert Decimal 237 to Binary 11101101. To get supported DVD Regions 2 & 5. I am definitely missing something or doing wrong? What is the right way? Will you please kindly help me. Thank you. |

Yes, you miss binary operations. Zeros in decoded byte show SUPPORTED region. Scan for zeros as they are located at the playable regions. |

Hello Sir, In this topic I had asked 3 questions related to disc information. 1) DVD Region Mask related part is clear to me. First question is answered. Thank you once again. 2) Now I will discuss about, IsDiscDualLayer. 3) Sir, I have gone through reported Disc Type for one of the protected DVD Video Dual layer DVD. It's Disc Type is reported as DVD ROM(128). So how to check Dual Layer DVD ROM. Yes there are enum values STARBURN_DISC_TYPE_DVD_PLUS_R_DL & STARBURN_DISC_TYPE_DVDR_DL. But what about Dual Layer DVD ROM? Thank you. |

Hello, Yes, it seems that DVD-ROM DL discs are "outlawed":) we should investigate it. Regards, Dmitry |

There's a way to get number of layers reading dvd structures from the disc. But I don't think we need to implement one. dima (staff) wrote: Hello,
