The issue with the PPV's is that external data may be needed for the genre info, which would increase load time. That could require including other plug-ins which could impact overall performance as well. couch potato may have a way around that.
The idea with bringing back IPTV Stalker was to have a lightweight client as an alternative to the built-in PVR, and minimal configuration. Just to let people know, it may be time to freeze a version of IPTV Stalker that is 'feature poor' that would work universally.
