  • Bootcamp Time Difference Between Mac OS And Windows

    This is what you need to do in order to fix the time when booting in Mac OS:

    1. Create new file /sbin/localtime-toggle with the following contents:

    #!/bin/sh
    
    to_utc() {
    echo "localtime-toggle: Toggling to UTC."
    date -f %m%d%H%M%Y `date -u +%m%d%H%M%Y`
    }
    
    to_localtime() {
    echo "localtime-toggle: Toggling to localtime."
    date -u -f %m%d%H%M%Y `date +%m%d%H%M%Y`
    }
    
    trap 'to_localtime; exit' term
    to_utc
    { while true; do sleep 86400; done; } &
    wait

    2. Ensure that localtime-toggle is executable:

    chmod +x /sbin/localtime-toggle

    3. Create new file /System/Library/LaunchDaemons/org.osx86.localtime-toggle.plist with the following contents:

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
       <key>Label</key>
       <string>org.osx86.localtime-toggle</string>
       <key>Program</key>
       <string>/sbin/localtime-toggle</string>
       <key>KeepAlive</key>
       <true/>
       <key>RunAtLoad</key>
       <true/>
       <key>HopefullyExitsFirst</key>
       <true/>
    </dict>
    </plist>

    4. Reboot.
    At this point, your computer’s clock should correctly be set to UTC as Leopard boots, and reset back to local time as Leopard shuts down.

  • Bootcamp Problem on Windows 7 with Audiodg.exe High CPU Usage

    BootcampDid you recently installed Windows 7 on your Mac Book Pro and experience problems while watching movies or YouTube videos? This problem is comming from your audio drivers. It seems that whenever you play something on your laptop and because the microphone is always open your sound card is trying to eliminate noise and this causes audiodg.exe to use some times more than 30% of the CPU.

    So here is what you have to do to be able to use your laptop with no problem!

    Disabling Audio Effects

    In order to fix the high CPU usage, I disabled the audio enhancements processed by the audiodg.exe file. To disable the audio enhancements, use the following steps:

    1. Right-click the speaker icon in the lower right corner.
    2. Select Playback Devices from the menu. A list of devices should appear on the screen.
    3. Double-click the device that has a green checkmark. The properties windows for that device should open.
    4. Click the Enhancements tab at the top.
    5. From the list of enhancements, uncheck all of them, or click the Disable all enhancements checkbox.
    6. Click the OK button to save your changes and close the window.
    7. Click OK to close the Playback Devices window.

    Once I disabled the enhancements, the movie played without any issues. I also didn’t notice any difference in sound with the enhancements disabled. If I do want to use sound enhancements, I’ll stick to the the options provided in the application. Something else you could try is disable the microphone if you do not use it, although I have not tested this myself.

  • Digital TV (DVB-T) On your Media Center PC (MPEG4)

    Windows Media CenterAbout a month ago in Greece most of the TV Channels changed their broadcast type to Digital (DVB-T). I was waiting for this change for quite some time now since i have my Media Center PC connected at a Projector (720p).

    On the date of the change i turned my Antenna and started to search for the Digital channels from my Windows Vista installation only to see that my TV Tuner found all the channels, the TV Guide was dispayed correcly but no sound or image was displayed in any of the channels (some had only sound).

    After upgrading the system with the latest windows updates and also installed all the codecs i could think of I started thinking that the problem was with my TV Tuner (WinTV-HVR-1300). After quite some time searching in forums and blogs and even though most of the posts were suggesting that i need to buy a new more recent TV Tuner I found someone that was suggesting updating to Windows 7.

    After doing that everything worked as a charm. As it turns out Earlier Windows (up to Windows 7) do not support MPEG4 and H.264 for live TV. And there is nothing you can do that would work correcly other than upgrading your system.

    So if you want to be able to see DVB-T Channels with MPEG4 and H.264 Encoding on your Media Center PC you have to upgrade to Windows 7!
