I try a lot of codecs but i did not found one to see all movie without instal another codec.
What codec is the best?

There is no perfect codec that will play everything. FFDSHOW once configured properly with a directshow player will play almost everything.
The key is to install only what you need. If don't want to mess with codecs or packs, VLC is probably the way to go.

lolol, nnothing plays everything , ffshow personaly is so confusing to install so many weird programs i didnt know wtf to do with lol, i sugest you get k-lite codec pack full, it comes with windows media player classic, i guess windows media classic is the easyest to put codecs on or somthing

All I want to do is to play a few DVDs for my own use. I own the DVDs. I went and got several codecs online but Windoes Media Player still won't let me play the DVDs because of property management rights. I own these DVDs. I tried a bunch of codecs including "all in one" so I too would like to know which codec is best for playing my DVDs on a Dell Flat Sharp 20.1" LCD monitor. I highly recomend this LCD monitor. Still,all I want to do right now is watch some DVDs on my monitor. If anyone knows, thanks in advance for a reply.

Did you read this small guide: DVD Digital Copy Protection (Madness)? I'm afraid you need DVD Region+CSS Free or other similar software...

With VLC can I do a ... resize on image or to move subtitle under image? I try to do that with VLC 0.8.4a bat I can not do it. Can anybody tell me if this is posibile and how to do it.
