İf you are get rid of icefilms since megaupload is down then try 1 channel plugin it is perfect better then the all time icefilms
Agree that 1CHANNEL is better than the current version of ICEFILMS; but not better than ICEFILMS was when it was linked to MEGAVIDEO before they got shut down. Still this 1CHANNEL is actually 50% functional so give it a try. It will still be a guessing game about what item will play, given the streaming sources are always random. A good solution to trial.
A few people have mentioned this.
Any tips on how to install?
Idiot proof steps please. 
1) Assume you know how to install a ZIP or REPOSITORY plug in file for XBMC. If not then go ahead and read about others doing this. Will have to search for the locationor the file URL, as i do not have it. 2) You may have to change the buffer settings internal to XBMC to have it work well on ATV2. again do some google searching 3) just start using it. yes these are generic instructions, but expectations need to be controlled, and usually are by experiments with other plug in experience with XBMC.

This plug-in is very good… can have some improvements but i personally think it is better than the icefilms plug-in…
make sure you have the latest RC2 version of XBMC and that you have the advanacedsettings.xml file right
with the advance settings.xml where does this belong in the AppleTV file? Thanks
see the sinful iphone thread. it is buried in the LIBRARY\XBMC\ settings somewhere
Since using 1CHANNEL for a few days am thinking it is working well. just have to pick the right source at playback (usually a guess) and you can see the video stream you want to. make sure you have good bandwidth on your download end. DSL is not likely to be fast enough.
