I understand from reading some of the other discussions, the extend live recording feature automatically extends all live recordings by 50% of the scheduled recording. IMHO, 50% extension is excessive, and records too much extra with no way of modifying the time extended or stopping the recording manually (at least I haven’t found a way to stop it). For example, for a 3 hour football game, 1.5 additional hours are recorded, which is an excessive waste. Moreover, this may cause conflicts with other recordings.
Based on my experience with another DVR (Verizon FIOS), I suggest a feature set similar to this DVR. The time extension should prompt the user for the amount of time to extend desired at the time of scheduling a recording. This DVR provides 5, 10, 15, 20, etc…60, 120 minute extension options at the time a recording is scheduled.
For example, based on my experience if I’m scheduling a college football game, I typically schedule 1 additional hour since college football broadcasting starts late and typically never ends on the scheduled time even for games that finish without overtime. For NFL games, I typically extend by 30 minutes. However, I noticed the Tablo extends the time for live shows such as American Idol or The Voice I don’t want to extend at all since they never exceed the allotted broadcast time despite the fact they are live.
