DVD-RA71 and DVD-Audio/Video

Hello,
I have the Panasonic DVD-RA71 DVD-A/V player and this problem:
I've just bought a DVD that has both DVD-Audio and DVD-Video information on it.
It plays wonderful on a standard DVD-Video player (without the high-rez sound ofcourse), but when I insert it into my player it is recognized ONLY as DVD-Audio disc and the stuff that is in the Video part is NOT accessible!
Any idea how to fix this? How to make my player recognize the disc also az DVD-Video?
Thank you!

I had this problem only one time before. It happened because I bought the Superbit edition of Snatch and my DVD player wouldn't play it the first time I put it in. I unplugged the DVD player, plugged it back in, and it played fine. Very weird and I'm not even sure it had anything to do with the DVD being Superbit, but it is the only one I have the is a Superbit so it would be a strange coinsidence if it wasn't because of that.

Thanks, but I don't think it would work for me, because it is OK to launch my DVD as Audio, but I would like to launch it as DVD-Video aswell...
