@ Kerry56 , VLC seems to play fine on my os. I usually use the slider to FF because the arrow controls are not good. What I like about VLC is it is one I don't need to use AnyDVD HD to play a commercial DVD . SM player is another one that doesn't.
The DVDFab giveaway plays OK & doesn't need a seperate decrypter.
The rest I have need AnyDVD HD . The reason is I don't set a region on my DVD drives.
If I did I think the other players might play a commercial DVD without AnyDVD HD enabled. I figure I have it anyway why not use it.
It is WMP10 that is choppy . I have WMP11 on Vista & it plays OK.
I'm still not a fan of WMP .
Nero is OK.
In a pinch the viewer in DVDShrink works full screen.
I can even use WinAmp but on a commercial DVD even with AnyDVD HD it may play a different language track & has not control over that. Since they didn't intend for it to play DVDs.
I don't have any payware players on Vista or W7 but I have an older version of PowerDVD on XP. From what I've seen posted Arcsoft TMT5 is a good player.
Media Player Classic Home Cinema works fine too.
I probably should give Pot player a test & haven't because I already have so many.
