As it says on the download page, don't update -- the GOTD key works with this specific download version. Also, looks like those who run more than one Windows acct or profile will want to register in each profile where they plan on using the converter.
Like Aiseesoft Blu-Ray apps, this installed the hacked Toshiba UDF driver in the XP VM [Virtual Machine] so XP can understand the UDF 2.5 Blu-Ray discs use. Unlike the Aieseesoft apps the driver installation *seems* to be only during install [rather than on program start], though I didn't test thoroughly.
Tipard Blu-ray Converter is your basic ripper to convert DVD/BD audio/video to other formats -- it's not a copy app like what was offered the other day, so you cannot access the original audio/video files. If/when backing up one of the DVD or Blu-Ray discs you've bought, if the audio/video file itself is too big to fit on the single-sided disc you want to burn it on, you'll have to re-encode anyway, so assuming your player works with the converter's output not a big deal. [Just what makes a video file Blu-Ray compliant is a bit of a mystery to us commoners outside the industry. Many Blu-Ray creation [authoring] apps have built-in compliance testing that is not always 100% accurate -- AFAIK most people just encode AVC/AVCHD, use something like multiAVCHD to put it in a proper file layout, put that on a disc, & if their player handles it, Cool.]
