    Like I said above, Dell probably locked out the ways that you overclock. Most Dell's in general cannot be overclocked.

    ok fine.

    Can someone explain to me what the difference between 1-pass CBR and 2-pass CBR is for Windows Media Audio? Is there a difference in audio quality between the two?

    What part of this don't you understand?

    Two-pass encoding is an encoding method available with some codecs, like the Windows Media Video 9 codec. When you use two-pass encoding, the codec processes all of the samples for the stream twice. On the first pass, the codec gathers information about the content of the stream. On the second pass, the codec uses the information gathered on the first pass to optimize the encoding process for the stream.
    In the Constant Bit Rate encoding mode, files that are encoded in two passes are generally more efficient than files encoded in a single pass. Quality-based VBR, which is one pass, produces more consistent quality than bit-rate-based VBR, which is two-pass.

    You cannot use two-pass encoding on live streams.

    er, does that make 2 Pass Filtering sound better?

    It's possible. To me, it sounds like 2-Pass takes a stream, looks at it so it knows what its about to get hit with, and then can make better decisions about how to use resources (CPU & RAM) to deal with what is coming it's way. It's possible that this just speeds things up, and its also possible that this just makes things run much more smoothly. For example, lets say you're going to Canada for vacation in February (why the hell you would do that is something that I may never know), and lets also say youre going to drive. You know that Canada is North of you (I'm in Indiana, hence my example). While you could just hop in a jeep and try driving North over hills, rocks, trees, streams, and small fluffy animals, most of us would rather get a map, and follow a highway. I personally think that that is what 2-Pass does, it basically makes a map for itself of whats in front of it, so it can make sure it know's what it's doing. I could be talking out 'o my ass though... these are just personal opinions.

    It takes about as long as it takes man. If your only experience is really with VB then youre going to have a hard time with it. I'm gonna guess that the Ogg Vorbis code is in C/C++ which is probably pretty difficult if youre only starting VB because theyre pretty much nothing like one another.

    WHEE!!! I'm done with vBasic. Just graduated from my computer programming class. in two years, I'm officially taking AP Computer Science, where I'll learn--

    OH NO!! They only teach Java, not C++. DAM˝IT!!!

    Yup, and Java sucks. The main reason they're doing that is probably the same reason everyone else is, including my college: To make sure you learn Object-Oriented Programming.

    now don't be so harsh on java, it is a really well done language, and it has almost all of the good sides of C, and a few extra tricks up it's sleeve... mainly the extreme portability, so if you write something in java, it will work on any computer with java virtual machine, not just on windows, but on mac, linux or whatever you're "driving"...

    and no I'm not saying that you should quit C and go for java, but that you should show some respect for a very well concepted language, and as another fact it is a lot more easier to teach and learn, because people get lost easily in C, and I think that you would have to agree that it is not for everyone...

    C does have it's practical advances such as it is very spread and you can easily find help for any problem you have...

    enough with the yapping, I'm done

    and yes I do know what is dAP written in, before you ask...

    dAP was made in C or C++?

    isn't Visual C++ object oriented?

    C++ CAN be Object-Oriented at times, but the language does not require it to be. Java forces you to be Object-Oriented.

    And as for my dislike of Java, it is mostly the result of the teacher that I had for it. He read us PowerPoint presentations to "teach" us.
