I'd be grateful if you could tell me if the attached mp4 files have the same out-of-sync issue on your Desire. They do on my HD2 but they play fine on a PC or the older HTC Touch HD. It may therefore be a Snapdragon chipset issue.

Started noticing that most videos I play from youtube whether though the built in app or the flash player are out of sync, not sure what's going on. Some videos are worse than others but not seen one that was perfect.
Also had the youtube app freeze a few times on me, for example when the unable to play video window pops up. Had to kill the app.

So is this a more general issue of video playback for Snapdragon chipset phones or not? There's a whole heap of stuff on the issue, which affects both YouTube and other video playback on the HD2 here:

I really would be grateful if some folk could try out at least one the test videos on the Desire and let us know if it is definitely in sync or not. Bear in mind that it's a small delay so you have to watch/listen carefully.
Thanks.

I watched both of the drum videos on both my pc and desire and found them both very difficult videos to judge, in the first the female drummers sticks are moving so quickly it kinda looked out of sync even on my pc. In the second the lip sync actually seemed ok on my phone, but with the transparent drum skin it was difficult to judge when the stick actually hit the drum.
I am currently copying a load of mp4 videos to my desire to do some more testing. I have also emailed HTC with my sync problems with youtube (mentioned that similar problem has been observed on the HD2) and wait to here if they have anything to say on the matter.

This is now confirmed as being a general video playback issue on the Desire as well as the HD2. It's therefore more than likely a Snapdragon chipset issue.
For a lot more info check out this HD2 thread, particularly post 94 and onwards from Desire users.

I copied about 6 episode of a tv show onto sd card which were transcoded by Doubletwist, and they seem to play back fine, if there is any delay its imperceivable as the lip sync seems fine (I have in the past calibrated sync timing for HDMI and optical connections in home cinema systems so I like to think I would notice any major delay).
However the sync is a real problem for me on youtube and other streaming media, here the sound is almost always unbearably out of sync.

To prove once and for all whether it's just YouTube or not, you might want to try the two short videos in the zip file here:

The two clips are identical except one has had a deliberate 250ms audio delay inserted and one hasn't. Which one plays in sync on the Desire? Please let us know how you get on - thanks.

Well i just got the Desire, and vid 2 is much more in sync than number one,
Youtube is awful, iplayer a waste of time......
Considering these devices are sold on their screen quality etc, you would think you could watch a youtube video in sync, hell, Apple can do it on a touch, which is what i have to use for youtube, until I get the Ipad...........

Agreed the one with the delay added looks in sync, the one that plays fine on your PC looks out of sync. Anyone had anything back from HTC yet? I sent them a mail a couple of days ago not heard anything back yet.
Definitely not a Google Android issue - it's the same on the HD2. It seems to affect all devices with the Snapdragon chipset. The sync problem doesn't exist on the Touch HD for example.
If anyone's raising this issue with HTC, they will appreciate it if you include the two files as an attachment. Then they can see exactly what you're talking about and won't just tell you to hard-reset your phone or use a different encoding method etc.
Wonder if anyone with an SE X10 is having the issue, that has a snapdragon so would prove a point. Had a quick search and can't find any mention of the issue on the x10 though.
