TV Mounting Problems

So, that TV I got, turns out to have a non-standard back. Therefore, we’re having major trouble mounting it to the wall.

We got the LT-P326W (notice that’s a link). In the manual, it suggests the [URL=]WMTL3202 (also a link).

The problem with this mount is that it needs a professional to install it, because it doesn’t fit on regular studs. Check out the description on listing page (that’s also a link), which notes the sizing issues.

Because of the non-standard size, that appears to be the only possibility, which really is not possible for us.

Are there any other suggestions?
