Before I jump into the deep end of the pool and install this wonderful looking media app. My concerns are it's stability and my ability to revert my system back to it's pre-ubuntuTV state.

Are there any detailed 'un-install' instructions? or is my best bet to just do a complete backup and restore if anything goes amuk?

If it has been packaged correctly, by installing UbuntuTV using the deb package from webupd8, you should (in theory) be able to ppa-purge the PPA and this would restore your system.

i.e.

sudo ppa-purge ppa:nilarimogard/test3
sudo apt-get remove unity-lens-video

If you see the following error message sudo: ppa-purge: command not found then install the ppa-purge package:

sudo apt-get install ppa-purge 

However, as all PPAs are potentially destructive, a drive-image would be prudent to make, especially as UbuntuTV makes underlying changes to Ubuntu2D.

I've done some limited testing installing and ppa-purge the package. From initial testing, ubuntu-2D works correctly after uninstalling - i.e. the same packages upgraded to v5 are downgraded to v4.x that is standard in oneiric.

However - the warning should be still applicable - drive-image your hard-drive. Use it as an excuse to perform that regular backup procedure we all keep putting off... :)

+1, especially for the part about putting off backups. Another popular question right now has already inspired me to do that when I get home. –  michaelms Jan 10 '12 at 20:45
    
sudo: ppa-purge: command not found may be worth mentioning ppa-purge has to be installed. –  rlemon Jan 11 '12 at 14:49
    
I am constantly editing (or at least looking for places I can edit) questions but I never think to edit Answers. –  rlemon Jan 11 '12 at 16:46
    
After un-installing using the described method I am now receiving unmet dependencies errors. Is this expected? –  rlemon Jan 11 '12 at 17:52
    
I've looked on webupd8 and no-one is reporting the same. I've just rechecked on by virtualbox install. No issues. Were you connected to the internet when you did a ppa-purge? What happens if you do sudo apt-get --reinstall install unity-2d? Please can you post the errors (copy and paste) via the website paste.ubuntu.com –  fossfreedom Jan 11 '12 at 18:13

There are good instructions both for installing and uninstalling Ubuntu TV at www.WebUpd8.org, HERE. You're correct: removal is important!
