In FCP, let us have QuickTime MPEG-2 Player themselves included inside ?

Question

I) -
I started with Final Cut Pro 3, then 4 and currently Final Cut Studio 5.
It seems me to have known that the installation of these integrated softwares the alternative of the version QuickTime MPEG-2 player which is sold with share on the APPLE site.
However, it seems to to me that when I open some QuickTime videos, it that I am announced to me misses the module making it possible to read it and I note that it probably acts of reader MPEG-2.
Can you so really say to me to the installation of Final Cut Pro or Studio, I acquire the QuickTime
Components which enables me to read format MPEG-2 ?
I tried to make a search using "spotlight", nothing does not indicate to me that it is there well, nor that it is found in my system.
Can you say to me, in the discs of installations of CPF or Studio, where can I find the reader QuickTime MPEG-2 ?
Or if there does not exist and that I must buy it on the site QuickTime Components - Reader MPEG-2 Player?
Thank you for your information.
II ) -Indeed there are not enought precision in my first question.
To answer holds;
I thus have the version of FCP 5 installed on my PowerBook G4 last series and also QuickTime Pro.
All goes very well except that I thought that QuickTime Components MEPG-2 Player was installed obligatorily when we charge FCP.
I note the following phenomenon;
I except have in my opinion all the components of QuickTime that of QT MPEG-2 since I never bought it owing to the fact that I think of having it with FCP.
When I want to read a video QuickTime MPEG or avi or other QT all this master key very well, except that some times it appear the message following to the opening of film: :
"an additional software is necessary so that QuickTime can read these media. It is perhaps available starting from the page of the QuickTime components".
If I read this video, I see the pictures but I do not have any audio.
This same video if I play it by opening it in "MPlayer OS X 2",
in this case I also find the Audio sound, but never audio starting from QT Player for this video.
This phenomenon is not on all videos, but only that on someone.
So unless I make an error of reasoning, it seems to to me that that must come that I do not have QT components MPEG-2 Player.
What do you think about it?
And : In FCP, let us have QuickTime MPEG-2 Player themselves included inside ?
If "yes" : Where ?
Can you say to me in which files I find QT MPEG-2 in FCP ?
Thank.

Answer 1

QuickTime MPEG-2 component is installed with FCP
Not all audio formsts embedded in MPEG-2 files can be natively decoded by Quicktime and so will not play the audio in Quicktime Player. However, those same files may play in other apps which do not use Quicktime for decoding.
You can enable more file type compatibility if you download and install the Perian quicktime component ... it should allow you to play back most of these files in Quicktime Player
FCP does not support audio playback of "muxed" formats such as some MPEG2 files. You must "demux" these files first ... you can do this with MPEG Streamclip
