Can Someone See Where I'm Going Wrong???
I'm trying to digitize footage from my camera and I'm getting this
Here's my setup:
The footage was shot in HDV 1080i60. Is my Capture Preset wrong? Device Control wrong? What should it be? I've checked my connections and the camera. The camera is telling me that it's sending a DVout singnal in HDV10801. What to do??? Plus FCP controls the deck it just won't "see" the video so that tells me that the firewire is at least talking to from camera to computer. HELP!!!
OK, disconnect the camera from the computer. Power everything off.
Start up the computer, keeping the camera disconnected, and use Digital Rebellion's Preference Manager to reset your FCP preferences. If you have been making lots of changes to the ingest settings, with the camera connected, it is possible you have corrupted your preferences. Preference Manager is free, and you can archive your old preferences if you want to revert to them.

Next, keeping the camera disconnected from the computer, turn it on. Do you have the operator's manual for the camera? You want to look at page 75. If not, here are some highlights:
So you want to make sure iLink Conv is set to OFF.
Now that you have set your camera menus, and reset your FCP prefs, shut everything down, connect everything together, and turn everything on.
When you launch FCP you will need to reset your scratch disk and choose your Easy Setup.
See if this helps.

Use the String class for the employee name.
Use an array of objects for the employee records.
Calculate each employee's annual salary from the job category and hourly rate, using the following constant information:
Job category: Full - 40 hours a week
Part - 20 hours a week
Assume 52 weeks in a year.
Display each employee's name, id and annual salary.
Calculate and display the company's total amount for employees salaries.
Use the following information to populate the employee objects: Employee

Action Script 3, can someone spot where my code is wrong?
I want to have my characters controlled separately, with 'FireBoy' moving using the left, up and right keys and with 'WaterGirl' moving with the a, w and d keys. However upon editing my code somehow WaterGirl now moves with the right key instead of the d key. Please can someone spot where I have made a mistake and advise me on how to resolve the problem.

Put traces in the different movement function conditionals to see which is being used under which circumstances. You might consider putting the movement code into one function since they all execute when you process a keyboard event anyways.

I have an iPhone 4 and a 4th gen iPod linked to the same email address and apple ID. I am trying to change the email address on the iPod so a family member can use it but when I do it says it doesn't recognize the email address. Where am I going wrong ? I just want them to be able to iMessage and email without having to use my email address.
The procedure is Settings>Messages>Send & Receive at>You can be reached by iMessages at>Add another email address. The email address has to be a valid working email address, obviously. Apple should verify the email address and you have to go to the inbox of that email account, read the verification email from Apple and follow the inductions in the email in order to complete the verification. Then you go back to the settings, uncheck your email address and check the new email address to be used as the contact email address.

I am contemplating replacing my old Ipod with a 8gb touch which supposedly holds up to 1760 songs. In my ITunes library the average size of a 12 song album is 300mb which means I can get 27 albums x 12 songs is 324 songs. Where am I going wrong here?
There is about 6.9 GBs of free space on an 8 GB Touch for data storage. That translates to roughly 23 of your average albums.
Holds up to 1760 songs is based on the size of an average track which is about 3 to 4 MBs, whereas your albums have tracks averaging more like 25 MBs per track. I sort of doubt your average album holds what would be about 5 hours. -

I am trying to delete an XLS file from a network drive and am getting a message that says the file cannot be deleted because it is in use. I can't see where it is in use and have tried to reboot the computer to no avail. I can delete other files but several XLS files are giving me this message.
You said it was a network drive. So is someone else on the network using that same file or may have have left with excel still accessing it on their system?

Making a simple calc applet. Where am I going wrong?
Hi everyone. I'm taking a introductory java class over the summer and so far I've been doing pretty good in it. I've been able to knock out and figure out how to do most of the assignments on my own. But this latest problem is driving me up a wall. I think I might be making it more difficult then it is. I'm supposed to a take a simple calculation program, and then convert it into an applet with new button functionality and text fields. In the applet, there will be two text fields(input and result) and two buttons(Update and Reset). In the first field you put in an operator and a number. Then from there you hit the Update button and the new value is put in the second field.
For example. The program is defaulted to "0". So you put "+ 9" in the first field, then Hit Update. "9" will now appear in the second field. Go back to the first field and put in "- 3", hit update again and now the second field will go to "6." You can keep doing this all you want. Then when you want to start all over again you hit reset. Its sort of a weird program.
Here's the original calc program:
import java.util.Scanner;
Simple line-oriented calculator program. The class
can also be used to create other calculator programs.
public class Calculator
private double result;
private double precision = 0.0001; // Numbers this close to zero are
// treated as if equal to zero.
public static void main(String[] args)
Calculator clerk = new Calculator( );
try
System.out.println("Calculator is on.");
System.out.print("Format of each line: ");
System.out.println("operator space number");
System.out.println("For example: + 3");
System.out.println("To end, enter the letter e.");
clerk.doCalculation();
catch(UnknownOpException e)
clerk.handleUnknownOpException(e);
catch(DivideByZeroException e)
clerk.handleDivideByZeroException(e);
System.out.println("The final result is " +
clerk.getResult( ));
System.out.println("Calculator program ending.");
public Calculator( )
result = 0;
public void reset( )
result = 0;
public void setResult(double newResult)
result = newResult;
public double getResult( )
return result;
The heart of a calculator. This does not give
instructions. Input errors throw exceptions.
public void doCalculation( ) throws DivideByZeroException,
UnknownOpException
Scanner keyboard = new Scanner(System.in);
boolean done = false;
result = 0;
System.out.println("result = " + result);
while (!done)
char nextOp = (keyboard.next( )).charAt(0);
if ((nextOp == 'e') || (nextOp == 'E'))
done = true;
else
double nextNumber = keyboard.nextDouble( );
result = evaluate(nextOp, result, nextNumber);
System.out.println("result " + nextOp + " " +
nextNumber + " = " + result);
System.out.println("updated result = " + result);
Returns n1 op n2, provided op is one of '+', '-', '*',or '/'.
Any other value of op throws UnknownOpException.
public double evaluate(char op, double n1, double n2)
throws DivideByZeroException, UnknownOpException
double answer;
switch (op)
case '+':
answer = n1 + n2;
break;
case '-':
answer = n1 - n2;
break;
case '*':
answer = n1 * n2;
break;
case '/':
if ((-precision < n2) && (n2 < precision))
throw new DivideByZeroException( );
answer = n1 / n2;
break;
default:
throw new UnknownOpException(op);
return answer;
public void handleDivideByZeroException(DivideByZeroException e)
System.out.println("Dividing by zero.");
System.out.println("Program aborted");
System.exit(0);
public void handleUnknownOpException(UnknownOpException e)
System.out.println(e.getMessage( ));
System.out.println("Try again from the beginning:");
try
System.out.print("Format of each line: ");
System.out.println("operator number");
System.out.println("For example: + 3");
System.out.println("To end, enter the letter e.");
doCalculation( );
catch(UnknownOpException e2)
System.out.println(e2.getMessage( ));
System.out.println("Try again at some other time.");
System.out.println("Program ending.");
System.exit(0);
catch(DivideByZeroException e3)
handleDivideByZeroException(e3);

}I'm not getting any compiling errors or anything and it launches, but it doesn't work at all. I'm sure it has something to do with the calc program and the applet actionevent. I just don't know where to go from there. Can anyone tell me where I'm going wrong? Or even make sense of what I've posted. I know its a lot. I've been looking at this thing for a day now and its killing me. Any help would be greatly appreciated. Thanks.This is a mistake
public void actionPerformed(ActionEvent e)
Calculator clerk = new Calculator( );
try
clerk.doCalculation();You don't want to create a whole new applet every time anyone pushes a button.
Make whatever changes are neccessary so that you don't have to create a new applet in your actionPerformed -
I've just started using the App Tabs. I think this feature could be handy but why are the sites not updated when I start Firefox. Now I have to manually update the site which is somewhat of a downer. Does any of you know where I'm going wrong?
To answer the post title FireFox save all downloads automatically in the download folder, which you can find in the Documents folder. If you want to choose where to save your downloads go to tools>options>check always ask me where to save files.
Secondly, I am assuming you have IE 8 installed as this is the only version that supports this fix that is currently not in beta. Go to control panel>internet options>advanced tab and reset the settings at the bottom. This may or may not fix the problem but it is a good first step. -
Can someone please tell me what's wrong with my feed?
iTunes isn't updating with my most recent podcast, and I can't see what I've done wrong on my feed.
Can someone help
www.ministryofslam.com/feed
https://itunes.apple.com/gb/podcast/ministry-slam-pro-wrestling/id301376618
It's "Bonus Podcast" that isn't appearingAt the beginning of the entry for the episode of 21 November you have the opening 'item' tag in twice. This is sufficient to render the feed unreadable and so it's turning up empty when subscribing and the Store is not updating.

I updated the latest version of iTunes today and it has a new look. That's fine but I can't see where to click to synch my ipod after downloading music or podcasts. It was always easy.
It might make it much easier on you if you enable the sidebar in iTunes. Launch iTunes and go to View>Show Sidebar. With iTunes set up like that, it should look a lot more familiar to you. You can select your device name under the devices heading and then go through all of the iTunes panes by clicking on them at the top of the iTunes Window.
My screenshot shows my iPad, but it works the same way with an iPod. -
I have snow leopard 10.6.8 and want to get on iCloud which requires Lion... should I buy Lion at $29.99 now and upgrade to Mountain Lion when available (I can't see where it is available for download yet) and what is cost of upgrade to Mountain Lion? Or should I simply wait for Mountain Lion?
I would wait for Mountain Lion to be released. According to Apple, Mountain Lion will be released by end of July 2012.
It will cost you only $19.99 to upgrade. You can find all the details at the following link...

Please can someone tell me what is going on when I get this message for the Time Capsule?
Yes, this is because Lion or ML which you are using have lousy networking.
The trick is simply reboot the TC..
Or on Lion use the 5.6 utility and disconnect all users.
For ML sorry.. Apple decided you don't need that function any more!!.

Read C12.. I think C17 is also related. -
My icloud storage is full but i can't see where all the data is.
I am using an iPhone 4S. My iCloud (free) storage of 5GB is approaching full usage. When I try to free up some space, the documents and data only amount to less than 20MB. I can't see where the rest of the 4.88MB is used and is totally invisible to me. Please help
Hey Dragonfly1981,
Welcome to Apple Support Communities.
Take a look at the article linked below, it provides a lot of great information that will help you find out what’s taking up the other 4.8 GB of data and choose what you want to be backed up.

Listening to XM and/or Sirius Radio Streams on iPhone
Hey everyone! I did a little research today, and found an easy (relatively) way to listen to XM or Sirius radio on the iPhone. First off, this is NOT a hack, and requires no installs on the iPhone. All this requires is a Windows PC (sorry, mac-users.
