First of all you would think that you can simply login to Dolphin 7 Administration. Head on over to:
Modules
-> Flash Apps
-> Comments Video Player

And, simply disable it and the Record a video comment link would be gone. Unfortunately it doesn't work like this, but hopefully in the future it will be that simple.

Rather than going through .js files or lengthy and possibly confusing .php files and code one thing you can do is simply hide it by changing or editing one line of code.

Current Boonex Dolphin Version at the time of this post is:
Dolphin 7.0.9


You should first disable the Record a video comment in as mentioned above in:
Modules
-> Flash Apps
-> Comments Video Player

Then, click and change "Enabled" to "Disabled".





Secondly download and backup:
/templates/base/css/cmts.css

Then, open the /templates/base/css/cmts.css file with your favorite text editor or your hosts file manager.



find:

td.cmt-head-m a.cmt-post-reply-text {
padding-right: 14px;
background-image: url(../images/icons/cmt-reply-write.png);
}
td.cmt-head-m a.cmt-post-reply-video {
background-image: url(../images/icons/cmt-reply-record.png);
}
td.cmt-head-m a.comment {
display: block;



Change/Add:

td.cmt-head-m a.cmt-post-reply-text {
padding-right: 14px;
background-image: url(../images/icons/cmt-reply-write.png);
}
td.cmt-head-m a.cmt-post-reply-video {
background-image: url(../images/icons/cmt-reply-record.png);
display:none;
}
td.cmt-head-m a.comment {
display: block;


Save the changes back to your hosting account.

Be sure to clear the Dolphin 7 cache for the changes to take effect.

Refresh a page or post to verify.

The drawback is if you need to upgrade it is likely you would need to re-apply the changes after doing so. However, this is a fairly fast and simple one to do again if necessary.
