I have been following this forum as well as Doom9 for the last three months and I bought a good quad core PC with internal BR drive and the Toshiba HD-DVD drive (the XBOX 360 accessory) so I can jump from the DVD world into HD and really enjoyed my 1080p TV beyond the NFL I feel like I am back to 4 years ago to the days of VirtualDub and DivX so we could backup a DVD to a CD as the DVD media was too expensive! I have spent every weekend for the last 5 weeks trying to make sense of this. Anyway I now seem to have something kind of stable if I burn an ISO straight from the original disk to an HDD and play it pack with PDVD (imgburn and Deamon tools on Vista32). I have been trying also to load the movie folders from the HDD into PDVD (yeah I got version 3319a with update off and blocked by the firewall) with some success but not always (e.g. no luck with Shrek 3 HDDVD). Loading the movie file itself (Feature.EVO or the main m2ts file) will fail almost everytime in PDVD with various error messages depending on type of disc and encoding (VC-1, AVC, etc...). So my ISO question is: Has anyone have success in creating an ISO with less than the full movie folders? For example with only the main feature movie? And then mount it and play it back in PDVD? I would not mind saving some space on my NAS while knowing that it will work everytime. At the same time does someone know why it works when you create the ISO from the original disk but does not work if you create the ISO after ripping using anyDVD-HD? What kind of mechanism anyDVD provides to make it work from original but it will not work from HDD? This is really mysterious to me (oh and yes I use UDF 2.5 and Nero 8 and all that so this is not the issue...!) Thanks!
