I recently looked into Tablo, as I'm interested in replacing my aging Channel Master DVR.
My concerns, that I believe haven't been resolved, are the lack of a "watch pointer"; essentially the DVR doesn't keep track of how much of a recording that you've watched. When you go to resume viewing, it will start from the beginning. This is basic DVR functionality...the first DVR's on the market over a decade ago had it.
The other issue is the lack of Dolby digital sound support. Unless there has been a recent change, Tablo only passes two channel stereo.
These issues may have been resolved with a software update...and if any Tablo owners could comment, I would appreciate it. Though I believe that Tablo is mostly focusing their software update efforts on expanding compatibility with more platforms, rather than functionality updates.
