TiVo's write to hard drive first, then playback from the written material.

HR20 plays back the live stream, and wirtes to the buffer 2nd (or more accurate, splits the signal internally and does both at the same time)...

Hmmm! Could this be why DLB isn't implemented on the HR20?

Or to keep in sync with non-dvr products playback...

As if you are watching the same channel in another room, on a non-DVR... you can hear almost an echo effect.... that was a big problem for me, when I had the TiVo product...

It was weird.. (both directions... could hear something early out of the other room, or get the echo effect).

Now, it is nearly in perfect sync.

Interesting indeed.

Which brings this question to mind:

The intent of write/read for "live" was to allow trick play. IOW, that's how Tivo can jump back 8 seconds or pause "live" TV. How would a system that did not do a prior write/read accomplish that?

I noticed that and actually have the same peeve that you did, Earl. Very interesting and cool stuff to know.

And you imagine that engineers designed the dvr internals just so the video was in sync with non-dvr video, me thinks you give them too much credit.

Okay.

First, Earl *talks* to people at DirecTV who tell him things.

Second, it is not unusual. My cable DVR does the same thing for the same reason. The only difference is that when you switch from buffer to live and back, there is a momentary black screen. The HR20 keeps picture up and may have a bit of a still pause when switching to buffer (it doesn't seem to go back to full live without changing channels).
