I have been ripping BD movies to my HDD and play from same HDD perfectly fine. I just got one of those LG combo HD DVD/BD drive and still able to do the same, BD ripped and play from PDVD only, but not HD DVD. When I played HD DVD, PDVD will just disappear... I am thinking it might be the HD DVD setting of my AnyDVD is not correct. I am sure someone here successfully ripped their HD DVD to their HDD and play fine from their PDVD 3319a. If you are the lucky one and reading this post now, can you please share with me that which box you checked and unchecked in your HD DVD setting in your AnyDVD icon? Or if you have some ideas other than the AnyDVD setting I can try, I really appreciated. AnyDVD 126.96.36.199 PowerDVD 3519a Many thanks in advance.
