This is great stuff. Where did you get these numbers? How can I get these stats for TWC in NYC? Sorry if you've posted this before.
I discussed this and refined my method for finding these numbers in a thread entitled "Some rough content bitrates derived from cable DVR filesizes
". Actually, the discussion started far back in this thread and I split it off.
My experiment continues---my methods have become extremely streamlined. I always have my PDA in the living room anyway (I read e-books on it and play games), so I keep an intermediate data file in it, as a comma-separated list of values: network, duration in minutes, size in gigabytes, date, time, program name. At the bottom of this file, I keep blank templates for the series that I watch regularly, with their networks, times and name already filled in and I change the month on all the templates every month. To make a new entry I just copy a template to the top of the list and change the date and filesize (and occasionally the time). It's a little more work for movies, but I have partial templates for the movie channels as well.
Every few days I sync the PDA with my PC and merge the completed entries in the list with a cumulative list in a text file. I use a Unix sort utility in Cygwin to sort it by the network, program, date and time fields (in that order), for my own convenience. I have a Excel spreadsheet linked to this comma-separated file which updates itself to the list automatically when I open it (or on request, if I update the list while the spreadsheet is open). In the spreadsheet, I have a table to calculate simple statistics for each of the networks, and a table with stats for each of the television series that I watch (and some that I just record for the data, like 24
I would love it
if other interested people in other cities would log some data like this so that I'd have something to compare against. If you're interested, you're more than welcome to any of my material and my Excel spreadsheet.

I believe that the DVR holds a portion of the disk out of its reported "free file system" space which it uses for these buffers. I think that the maximum length of the trick-play buffer is not an absolute number of minutes, but a filesize--it will be half as long on HDNet as on Fox HD. Mine also seems to stop buffering the second channel if I don't use 2 channels for a while, as you suggest. If I hit the "Swap" button then, I'm on channel 2 (QVC or something like that), with no accumulated buffer. It always has the last channel either recorded or viewed buffered. Mine is always "on", by force of habit, since TiVo needed my old box to always be "on". There's been discussion here, though, that it doesn't stop buffering just you put it into standby mode.
