Okay, a quick look at the Album-Admin page and now I see your confusion. I will make some further comments later tonight after looking at your layout online. (FTP) I have a list started and it will take some work to figure out the changes. But, after looking at the real code, I will have a better attack plan.
So, first, finish up the Video-Admin page. Then, if you have some time, here are a few first-look comments on the Album-Admin page.
(Note, I am saying Video-Admin and Album-Admin from now to tell them apart. The "Playlist" is just an internal term we will use for the actual JW Player text that is used only by the database...)
Album-Admin, first same as the video side, if you have a button to Create-New-Album, then you don't need it in the drop down list. (Perhaps it should actually be a button?)
The drop-down should be "Select your album" not video. This drop down should contain any "ALBUMS" that have been created so far, not videos. (Pulled from the database of course)
To explain Albums further so we are on the same road... There is only three main parts to the Album-Admin page. First, the list of Albums already created. When one is selected, there would be Album-Name, Album-Description and the list of videos that were placed into it. Then, we have to add some buttons for several options such as deleting a video from the album or adding a new video to the album. (Remember, the album will be what we are actually going to play in the player page for people other than the ADMIN.)
Okay, now the confusion part... The middle square of the Album-Admin is the "album" section. It allows the admin to select an album to work on or create a new one. Once one is selected or created, it should list the list of videos that are available and the list of videos currently used in the Album. So, actually, you need two lists. One that contains ALL of the videos that have been uploaded and a second which is just the ones previously selected for the current Album. So, there is some work needed there...
I am curious if you have ever used tables must in HTML. I think that it would make some of this easier to display. But, I am weak in CSS and see you use it well. Just a thought...
Well, will look at the file layout and talk to you more later... (Enough for you to play with for now...)
