My DVD player is supposed to play avi videos, but it often doesn't telling me that the file format is not recognized. I suspect it's because it's the wrong codec. How can I tell what the codec is before I burn a DVD? And how do I get a workable codec? Thanks for uour help!

I am not a computer savy person. I just need to plug in and have the machine do what it should do.
Not a problem, but that indicates you have a lot to learn.
File extensions like mpeg, mp4., avi, wmv, etc. are just wrappers. It is like a box the audio or video content is placed inside. The audio and video content must be encoded with a codec before it is placed in the box. There are thousands of codecs. Not all are installed on your Mac. You must have the same codec installed that encoded the video in order to play it. So, while Quicktime does support mpeg wrapper, it may not have the codecs to decode the internal video.
Some programs have lots of the codecs available to them, like VLC, Niceplayer, MPlayerX, etc.
You can also get "plug-ins" for Quicktime that add codecs to Quicktime, like Perian. Although it is no longer being developed, Perian still works well.
Why is it so difficult? Probably because they are always working on ways to compress the video to get better playback.

How can I tell what the iTunes build is before I download?
I am having difficulty finding out what the iTunes build is for the current download from the Apple site. I am running iTunes 7.6 (29); I assume the "29" is the build for my installed version. I also assume that Software Update will ignore build changes unless the version changes.
I do not want to download and install the current iTunes build unless it is different from my currently installled app. How can you tell what the specific version and build are from the Apple download site?
Thanks!I am running iTunes on Leopard.

Non-Global Zones - how can I tell what the Global Zone is
Hi,
I have a host that I know is a non-global zone (ngz). I can ssh to the ngz as root or a non-privileged user.
But once there how do I know what the host name for the global zone is?
I could probably run a script from all global zones to report all running zones and so I'd know that way but I have a specific need to know from inside the ngz.
Thanks!

That's a built-in security feature; and I know of no way to circumvent this mechanism.
I had some hope that there was a way to 'see' at least the global-zone information from the zone. From the shell the 'zone' commands are available ..
:# zoneadm list -cv
ID NAME STATUS PATH
48 hostname_svn running / So it's at least aware that it is a zone, even if it can't tell me anything else about itself. I can still go the long way around to get the information for my need, thanks.
The global zone is the only thing that can see everything. The non-global zones can only see information specific to their zone.
This is by design and it really is a security mechanism. You don't want the zones running outside of their boundaries and information about the global zone (or any other zone) is outside the boundaries of a non-global zone.

Generic wsdl - how can you tell what the field assignment is?
When using the generic wsdl, it seems that your custom fields are mapped to fields such as:
customcurrency12
customtext4
When accessing the asset class, how can tell what field is assigned to what custom value? When I look in the admin > application customization > asset > asset field setup
I can see the list of fields and field types but not the number on the end so that I can assign it in my web service code. Is there a way to see what your custom fields are mapped to (i.e. custom standard discount is mapped to custompercent11)
Thanks in advance any help you can lend on this,
AspnetDevYou can use the getMapping web service to get al ist of all the fields for a record type. for each field you get the ElementName (which is what you get in the generic wsdl) and DisplayName which you can use it to match to your fields.
<Field>
<DisplayName>My Custom Field</DisplayName>
<ElementName>CustomText74</ElementName>
<DataType>Text (Short)</DataType>
</Field>

How can you tell what the OS is?
I have an OS on an external drive. Is there any way to tell what version it is without actually booting into it?
Thanks very much.Open Disk Utility, select the disk from the sidebar, and click Info. This won't work for Logical type volumes; I'm not sure if it works for Windows, but I'm assuming you are talking about OS X on the external drive.

Messages: How Can I Tell What The Unread Badge Is For?
Often recently I end up with a "1" in the unread badge for Messages (ie, stuck to the dock icon and the command-tab icon), and cannot get it to go away or figure out what it is for. None of the visible conversations have the "unread" dot next to them, and I can't just open up one-by-one all the closed conversations from my buddy list to randomly guess if they are the source of some notification.
Is this just a weird UI limitation at the moment, or is there a way to figure out what it's talking about? Right now I have to quit Messages to "clear" this distracting (and indiscernable) notification?
I can't take a screenshot of the command-tab feature, but here's what I mean as it appears in the dock.
Edited: Clarified product referenced in TitleHi
At present this happens to some people.
In some cases the number can be a Minus figure.
It can be improved by deleting com.apple.imservice.iMessages plist and then restarting Messages.
You do this by having the Finder as the App on the Menu Bar.
Use the Go Menu > Go to Folder and type ~/Library/Preferences in the dialogue box that appears.
Find the .plist and drag it to the Trash.
Restart Messages.

PAL or NSTC, how can i tell what format the vid clip is?
The 2nd abbreviation might be wrong...
concerning vid clips
How can you tell what format clips are in before iMovie tells you?
I don't want to combine the formats and cannot figure a way to tell the difference before trying to burn the dvdAt the top of the iMovie project window it will tell you by giving the name you gave to the project as well as 'DV NTSC, or DV NTSC Widescreen.
Somewhat confusingly, when you set your choice of NTSC or PAL in iMovie's preferences when starting a new project (you can't switch later), these are only identified as 29.95 fps (which is NTSC) and 25 fps (which is PAL). Once you have set that, all iMovie projects you start will default to the same until you change it. You cannot combine the formats in the same project.
As you are in the USA yours will probably default to NTSC which is the TV system you use there. In Europe we set it to PAL which is what we use here.
A bit rudely, we also say that NTSC stands for 'Never The Same Colour Twice'!
PAL used to stand for 'Prolongs Active Life', but that was actually the tag-line in a dog food commercial! But they are useful mnemonics to remember them by! -

How can I tell what table(s) have the most transactions against them
Hello, in Oracle 11.2.0.3, RHEL 6 x86-64, how can I tell what tables have the highest transaction activity?
Picked "Objects" because I could not find a space related to performance tuning
Humbly,What version of Oracle are you running (standard or enterprise)?
Easist system is to run an AWR or statspack report. If you run either of these you will see sections on segments (so segments by logical reads, physical reads) which is easily digestible.
v$segment_statistics will also give you a breakdown on segment access. -
I just got an IPAD2 on Saturday. With the Mac, I could always tell when programs were open/running by going to the menu bar. How can I tell what programs are running in the background. I am struggling with not being able to go to a menu bar at the top
You can see which apps are open and/or recently used by double-clicking the home button to bring up the taskbar at the bottom of the screen (not all apps that appear there are active) - you can then close apps on it by pressing and holding one of them for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Mail app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar. If you have an app 'open' on-screen then it won't appear on the taskbar, you will need to go back to the homescreen first, and it should then show when you next open the taskbar.

How can we tell if the iphone is already fully charged in ios7? Even if its 100% the thunderbolt icon is still displayed. Not like in ios 6 that we will know when to unplug the charger because there is an indicator.
For those who seem unfamiliar with what is being asked:
On iOS 6 and older, just because the phone reached 100%, didn't mean it was Fully Charged. The way you could tell was the lightning bolt symbol that indicated the device was charging would change to an outlet plug when the device was not only 100%, but also stopped accepting further charge. This symbol switch would occur anywhere from 5-15 minutes after the device already was displaying 100%.
Now, on iOS 7, while it still reaches 100% with that same lightning bolt charge symbol, during the 100% point, it never switches to the plug symbol to indicate the charge period is totally finished.
Can anyone confirm if there is a way to see this charge completion in iOS 7 since it appears that there is no longer a symbol for it? Is there any indication that Apple may have changed the charging display so that now it only displays 100% when it would have previously displayed that plug symbol? -
