I've never had any problems on my PC playing DVD discs before, I even thought my PC can play DVDs better than any home theater system, until I've bought a descent TV, a descent DVD player & a descent sound system. There is nothing wrong with watching on the PC, a PCs processor can work a lot faster that the one found in DVD players, but the Quality of the TV & the sound for sure beats the PC by far, no PC can give you the same sound quality via the subwoofer / Video quality via the screen like a descent home theater system. Thats why plugging in earphones to the PC suck, because the quality is low, but, plugging them into the TV / DVD player makes it feel more "Real". My opinion is: If you have a descent home theater system, use it... OR If you only have a PC, then use it instead. Sound card manufacturers, especially Realtek, still have a lot to learn before they can compete, even the aftermarket sound cards cannot compete to the genuine, descent home theater systems, it just doesn't feel the same, trust me, if you have one, you'll know what I mean... Even a cheap home theater system can prove a lot.
