I've had a vlm file that's been working for a very long time in Linux Mint 15. I believe Mint 15 was based off Ubuntu 12. The vlm creates a mosaic of 6 vl42 devices which use 3 separate hardware devices and hence 3 different drivers. One device is a 4 port card. This had been working fine until I upgraded to Mint 17, which is based off Ubuntu 14. Anyhow, here's the vlm file:

Note that the only difference between what I've posted and the script is that the script tries to run v4l2-ctl on the devices to make sure they're configured properly. This was necessary in Mint 15, where vlc 2.0.8 was used, but now it does not affect the stream at all.
Anyhow, since upgrading, the stream no longer works. Right now the "webcam" device is the only one showing a proper picture. The bttv camera seems to not have set the correct standard, as the image is green and fuzzy, and the other 4 on the saa7134 are completely blank. I've read a few other posts where it's been suggested this is a driver issue, but other apps such as mplayer and xawtv work perfectly with these devices. This leads me to believe it is NOT a driver issue.
Here is the output when I run the script with -vvv (The forum complained that I exceeded the 60k max character limit, so I put the file on my own web server):

I've also tried the 2.2.0 PPA, which installed a 3.0.0-git version, but this seg faulted. I'm willing to try the PPA version again if new builds happen nightly, as the PPA seems to suggest they do.
I've even tried running the old vlc in a chroot on the new machine (I had saved the previous root filesystem under /old). This yielded the same problems, where the v4l2 devices simply were not configured properly.
I'm hoping someone has some insights. And BTW, I'm lurking on IRC in #videolan on freenode as Primer. Feel free to contact me there directly.
Thanks,
Daniel
