If they all say Average, just pick one. It doesn't really matter where the layer break goes unless you don't have seamless layer breaks. Because depending on where the layer break goes, if it's not seamless, you'll get a pause in the playback. And if there's dialogue there, the audio will pause.
Don't use Verbatim Life Series. They're CMC Magnetics, which is junk media. The only reliable DVD+R DL media (I'm guessing you're using DVD+R DL?) is Verbatim's DataLifePlus, which you can only find online. When you say you used the next quality up of Verbatim, what exactly does that mean? If they're not DataLifePlus MKM media, then it will probably still not be good.
The pauses at the layer break are caused by layer break pauses. When you set the layer break, choose Seamless Layer Break. Now, sometimes, leftover layer break pauses are in the video. Or added by the authoring software that made the VIDEO_TS. I learned this the hard way. 10 years ago, I burned a bunch of them, not knowing about seamless layer breaks. Had to burn about 20 or so all over again without layer break pauses.
If after setting Seamless Layer Breaks you still get pauses at the layer break, you can use DVDShrink to get rid of the layer breaks. Doesn't always work, though, and you need to resort to IFOEdit. However, if you don't know what you're doing, you shouldn't mess around with IFOEdit to remove layer breaks. Believe it or not, some layer breaks are necessary. For instance, there's apparently a layer break pause at the end of every video stream, if IFOEdit is to be believed.
In the list of layer break positions, if you're offered to add a layer break at a .BUP file, I recommend choosing that. Barring that, choosing an .IFO file for the layer break. Generally, more often than not, you're only offered .VOB files in the list.
