Hi Dave,
For now that functionality has been pushed into V4 as it's imperative that we get V4 out asap.
Media Center has an inbuilt function to merge the inband times with guide listings, which worked for us 80% of the time, but due to some minor differences in titles and schedules it failed 20% of the time so we had to turn it off. Since then, we have developed an algorithm that will work even if the two schedules differ by the number of shows, or by title, which will be rolled out in V4.
V4 will be rolled out in stages, starting with the basics as we have now in V3, then adding in more UI features like 'New Shows', 'Popular', 'My Week' and 'My Shows', a replacement EPG UI, and more integrated content.
Cheers,
Luke
