[When I tried to post the first time, I got an error. Hopefully, this wont get posted twice.] I have some strange problems when trying to rip planet earth disc 1. Using the anydvd-hd ripper, I get a "error reading from drive:" error message about half-way through the disc. Thinking that I have a bad disc, I tried to rip another planet earth disc 1. I got the same error -- but now towards the end of the disc. I am using vista ultimate, anydvd-hd 18.104.22.168, and xbox hd-dvd drive. I tried a different computer (vista ultimate) and the anydvd-hd beta version and got the same problem. On a different disc ("the fountain"), I had the same problem ripping on one computer but no problems on the other one. I also used a friend's xbox hd-dvd drive and ran into the same problem. When I try to copy/paste instead of using anydvd-hd ripper, I first get a error that vplst000.xpl from the adv_obj directory cannot be copied (0x80070570 - the file or directory is corrupt and unreadable). If I skip copying that file, then the copy process copies most of the hd-dvd but throws a "the specified destination does not exist..." error towards the end while trying to copy a large evo file. I am copying to the local hard disk and there are no hard disk problems. The discs play fine using powerdvd ultra. By using different discs of the same title, different computers, different x-box hd-dvd drives, I still havent been able to pin-point what might be causing the problem. Any ideas re: what might be going wrong?
