It would be great to see a feature that makes it more feasible to record a show that you are watching live. Currently you have to go back to the tv guide to schedule the recording and even then afterwards you would lose everything inside of the buffer.
For Roku one workflow could be, while watching the show you press the up button to bring up the mini guide, then press ok to record. Afterwards any content in the buffer that occurred during the time the show was scheduled could be added to the recording. Optionally, it would also be nice if there are conflicts preventing the recording that you can have the choice to cancel one of the other recordings without leaving having to leave the show to go back to the tablo interface.
