[thebest]

if i wanne rip some movies with dvd decryptor i get an error mssg
ASPI Command error
but i can still rip the dvd but when i burn it to a dvd-rw and try to play it with power dvd it says not valid file structure
and when i stop the decryting instead of let it go it give another error
Title Authentication failed
Reason: Failed to get Title Key
so is this my aspi driver that isn't working well or is this the protection of the dvd's? please help me out with this because i didn't had this error when i copy kiss of the dragon and that works perfectly and now i wanne copy the emperors groove(disney) and it gives that error??
even after the 2 errors it says cracking CSS what is that?

On the left hand side is the tools section. Go there and grab
forceASPI. Install.

i did and install it but still the same problem but what i wanne know if this is normal or not?? because the rip is done and i can play it fine with the ifoedit player
but i gane try it out with a new movie and if it still don't work when i wrote it on dvd then i think it isn't normal

once it is ripped and i open the ifo vts to play the movie in ifoedit it says no valid DVD-VIDEO volume could be located do you still want to continue and i press yes and the movie starts to play?? weird is this why it would not work once i burn it on dvd?

I have the same problem , no valid dvd-video could be located , but if I let it continue the file plays fine , but the dvd-r that is subsequently burnt wont play in my panasonic rv31.

anyone had any success with this standalone dvd player ??
