One commenter reports that in their reply from Sprint they were told that they mention the fps cap in the owners manual (though I haven't found it).
Given these responses, it's a lost cause.

That said, the HDMI port on the EVO isn't necessarily a slapped-on afterthought. Per the geniuses and magicians at XDA, it's a Silicon Image Sil9022a:

You might find
NeoteriX's results interesting:
What makes our 720p recording inferior (imo) to the iphone, nokia n8, and samsung galaxy?
As well as this follow-up in the same thread:
Also in that thread, a few of us were speculating that the 65 nm process technology would consume higher power and produce more heat. Close, no cigar - but very close.
Again, per XDA, there are several issues with the EVO's HDMI - for one, there's no sensing for an external device - or even a user-accessible on/off switch for it. That baby is always powered up, unlike the Droid X, if I read that correctly.
If true, then yeah, HTC has frequency-limited the chip for power and heat management.
So, yeah - the issue is really about power management, as we all suspected, and a big tip of the topper to the few, the proud, the XDA that seem to have proven that.
It all comes down to use cases. I'd be pretty happy with _most_ 720p _video_ at a steady 30 fps - despite 60 being an ATSC-supported mode.
Remember - Blu-ray players are at 24 Hz, matching 24 fps film source.
That's the justification HTC's using - if you notice, 29.97 fps is the NTSC standard.
I'm not ready to disbelieve a fix is inevitable. All we can do is stay tuned in for the latest results.

I also found NeoteriX's choice of test material quite interesting. You may have followed Buck from the beginning and already know the backstory, but if not -

That particular vid is at 24 fps.
