What is the computer configuration?
Where is your scratch disk set?
How much hard drive space for scratch? For Video storage?
Exact framerates/datarates you’ve tried.
EVERY setting in the MPEG export…
Formats you’ve attempted to export to…and any differences in behavior in various players.
What happens if you export to something crazy like uncompressed or QT Animation or even DVCProHD and THEN compress it to MPEG?
AND…as I asked you, have you imported the original project into a fresh project to see if the project itself is simply corrupted?

Like Jeff mentioned, H264 AVCHD can be pretty rugged looking on playback using the half-res decode setting for playback.
Yellow indicates that the footage SHOULD play back…but that status is not calculated based on any in-depth system assessment. It doesn’t mean that your system is actually capable of playing the footage.
As far as the playback frame dropping is concerned, I’m wondering if the pixel aspect is correct for the sequence settings…? 1280x720p square? Correct framerate?
What happens to the framerate if you drop to quarter res for playback?
Do you seem to have issues with any other formats playing back? XDcamHD? DVCProHD?
Half res 1280x720p AVCHD shouldn’t be a problem for full frame rate playback (pixelation for this format is common in sub-full res mode) in one stream…multiple streams will likely stress your single-socket processor, even with HT enabling 8 threads…and effects will immediately slow you up (is CUDA enabled on your display card?).
In my experience, AVCHD/DSLR footage seems to run much smoother with multiple physical processors.
For AVCHD, multiple physical processors trump multiple cores…and actual cores trump virtual (hyperthreading) cores for productivity…(since you work in visual effects, you’re probably quite familiar with this concept).
If the material came from a DSLR, the data rate increases to 50 Mbits/s and the decode is a bit more stressful and that could slow things down a bit…
Either way, these formats shouldn’t require a massively fast hard drive for the data rate, so it’s doubtful that’s the problem, even if you only have one 7200rpm drive, one stream should be no problem without effects.
…but H264 is a CPU load relative to almost anything else.

Are the “spots” it stalls consistent?
There is something wrong with some media or something inside the project…
Have you attempted to import the project into a fresh project? That’s the typical first troubleshooting step…

Well…you could export an uncompressed QuickTime file (or Animation or whatever) and take it to an FCP owner and have them convert it…
Or…assuming you have a HDSDI I/O card installed, you could rent an AJA KiPro outboard unit and output to it…and it will record a ProRes file.
Or…you can buy a Mac/FCS.
ProRes encode capability is limited to FCP owners and therefore…not available on Windows. Period.
I’m not sure why the DVD facility needs this type of file… Are they doing the authoring? Uncompressed would be as good and if it’s a massive file they want, that will certainly be massive…
As far as Mac users not being aware of what the NLE world can do outside of FCP…I don’t think they’re all that way, though when you run into a shop like that, it can be challenging.

Premiere Pro defaults to MPEG I-frame for a preview render codec…you set this up when you set up a sequence.
MPEG needs to have dimensions that are divisible by 8 in order for the block/macroblock encoding structure to work properly. that may have something to do with it…1746 is not divisible by 8.
You can change the codec, though I’d say that v210 or uncompressed will be a pretty oppressive file size at that frame dimension.

[Philippe Verdoni] “The problem that I have is not how to define a shortcut but it is that in the Timeline window some options are unavailable such as:
Go to sequence end
Go to sequence start
Play/Stop”…now I know I don’t understand the question.
in the list of keyboard shortcuts you’ll find:
“Go to Sequence-Clip End” shortcut: End
“Go to Sequence-Clip Start” shortcut: Home(These are applicable to the sequence or clip depending on what panel has the focus.)
“Play-Stop Toggle” shortcut: Spacebar (like all other NLEs I’ve ever laid eyes on…)
Is this really your question? I’m at a bit of a loss here…

From Adnan’s screen grabs, it looks like he’s on a Mac…
The most likely issue in my opinion is that you were in RGB in Flash, and Premiere Pro moves that material to what they call “YUV”, (which is erroneous…it’s actually Y’CbCr), or video colorspace…but in any case, the color palettes are not an absolute match and often this sort of conversion can create issues in workflows that require it…made even stranger with repeated passes back and forth.
Who knows why it would be fixed on YouTube…maybe it’s just that the browser is on a monitor that has some misadjustment that “corrects” the error?
…it’s pretty tough to use internet-sourced video as any sort of color assessment.

[Rick Connolly] “Would still like to get an explanation why these clips worked in CS4 and not in CS5.”
CS4 is a 32 bit application, CS5 is a 64 bit application…it’s 99% certain that you don’t have the proper 64 bit codec for CS5 to be able to decode the files.
Camtasia files were an issue for CS5 until they came out with a 64 bit version of the codec.

You have to click in the text field where the keyboard shortcut would be and type the key…
In the PPro CS5 help:

You’ll want to get a piece of software called “MacDrive” to enable your PC to read it…and make sure the drive can be connected by means other than FireWire 800.
…and in my experience the LaCie “ruggedized” portable drives with the orange bumpers are just plain bad news for cross platform work, so if he has one of those, I would require that the data be transferred to something else.
