You may wish to make people aware of a post I made detailing how to easily switch between different MP versions without disturbing your original install. It's in the Wiki here

This might encourage people to try tv3 svn's out more when they can do so without ruining a current working setup.
I have tried a few svn's with tv3/tv2 along the way BUT there is a problem that has been in svn for months whereby playing back some recordings will freeze as if paused on my machine. I then have to exit, re-play and try to jump over this point as it will consistently freeze at the same point. I meant to raise a bug report but never found the time to do it justice. I get no such problems with 2.2
I was unable to watch tv from a second seat over 54g WiFi using tv3, though over LAN 100 it worked OK though very slow to initialise and would often get confused. Though unable to stream live TV over WiFi, I could playback a recording via a share using MyVideo over WiFi fine.
The multiple channel recording got really confusing a lot of the time, just recording the same program on 3 diff concurrent recordings, also being able to step back to tv prior to the last channel change i.e from a different channel got very confusing and is IMHO not a good idea. If this facility is required it should be implemented differently eg if jump back to before start of 'current channels' timeshift, present a listbox of previous channels timeshifts in time descending order and allow user to select one (drop any less than 2 mins as they will just be surfing). I'd check out how MythTV handles this they do it quite good.
Timeshift disable should also be allowed which will instead use a 1 minute timeshift memory buffer (or allow user to alloc as much ram to it as they wish).
It'll be great when it is rock solid with a good web front end. I think some work should be done on optimising the user response times throughout MP, to make it run as slick as possible as some areas are still quite sluggish.
So for me, I use 2.2 and try an SVN every few weeks.
