For anyone who has not been following progress, the latest innovation in the WebIF command set is the shrink option (at the time of writing known as "squeeze" but due to change imminently). This removes redundant data from the recorded transport stream and thus the recording occupies less precious disk space, but it is a work-in-progress at this point. Savings are estimated at 20% for a StDef recording and 75% for radio. I'm sure Ezra will be along shortly to provide a reference to the relevant Wiki entry. I have pulled this out of the general WebIF topic to provide some subdivision of discussion. The relevant part of the WebIF topic starts HERE (click).
