Actually, some of the older models are still being 'blessed' with software downgrades, as TiVo updates them so they will no longer do the half hour time shifting if they don't have a contract anymore. Before the 'updates' you could use a DT Series 2 for a half hour time shifting machine.
The older models don't really need any software updates as far as I know, except for the Series 1s could use some work. But hardly anyone uses those anyway.
