Hey there everyone! Well, as the subject header suggests...I've been having a long time problem -- my dvd backups will play perfectly in my ancient stand-alone pioneer dv-525 dvd player...yet don't 'fully' work in either my htpc [toshiba drive I believe], or my regular pc [in either the pioneer slot dvd slot drive or my sony dru510a burner]. What HAPPENS is that when playing on the computers, if there is no stopping, rewinding, fast forwarding, or skipping of chapters BEYOND around half-way through the movie...then it plays fine...but anyting beyond that -- then I get an error from powerdvd saying that the disc is unreadable & have to start the movie over. Like I said, it works fine in my ancient DVD player...so I'm assuming that it must be some windows setting or so forth? I have used boht +r and -r media from different brands [ritek, tdk, etc...] and all give the same results. I am using xcopy platinum in xpress mode. Any help would be GREATLY appreciated...as this has been a constant and annoying problem -- thank you!
