Well gang, I've been working at this for some time now, and it seems there are some issues with the HD versions of YouTube videos. Previously, YouTube HD and HQ URLs required appending special code to the end of the source of the video. This hasn't changed, but originally, having the special appended code on a video that did not have a corresponding high res video didn't matter. The Standard Def video would play instead. This was perfect for AME, since the best suited option for this, the way RegExes work, was to have one definition for all resolutions.

This is no longer the case with YouTube videos, as now, if the higher resolution video doesn't exist, and the specia code is appended to the source video, the source video can't be found. There are issue with the Regular Expression needed to parse YouTube videos, so a second definition is not working out either. If anyone has found a more tenable solution I'm all ears, because right now, HD and HQ will not be in the next update.

OK,

How to fix the size of the embedded video????, it was working fine with the default one before i installed this plugin....after installed this plugin resized to small....i dont see any option to in the ame cp, so i just went to the youtube definition display and edited the width and height.
I have installed the latest stable version of this plugin and the base....im usin vbulletin 3.7.4

If your using 2.5 your Height and Width options are right there under Settings in the AME CP.

If you removed the $ameinfo[height] and $ameinfo[width] variables from the YouTube definition, then your global size settings will have no effect on your YouTube videos. This can be a problem if your planning on allowing videos in signatures, profile comments, etc.

No,

I'm using the version 2.0.2 (stable?)
Do you recommend to use 2.5?

Thank you DJ for your quick reply,
