Alpman: Thanks for answering the questions I had. Took a bit of searching, but I finally found the DVRHELP forum, and found the HD upgrade stuff. Thanks.
I'm dissapointed that you can't get the sat channels in the guide. I guess this recorder will be dedicated to local channels.
I'm curious just where the guide data comes from? Ie, does the info for all the local channels come in through one channel, or does each channel have only it's own guide data? Reason I ask, is when I did the channel search, the 7000 came up with 3 or 4 channels that I don't really get hardly a hint of a picture, ie certainily not good enough for it to extract guide data from, yet the guide data for those channels appear in my guide. This makes me think that perhaps if I LIE to the 7000 and tell it that I have cable, that it might give me guide data for all the cable channels, which would at least tell me what was on many of those sat channels, even though it wouldn't be able to go to them from the guide. I know that I could just read the guide off the DTV, but that means using a separate remote. I don't ever use my DTV remote anymore, as it is controlled by my unsubscribed TIVO., so it would be nice to have local and sat guide data all in one place.
Overall, I'm not that happy with the limitations that the 7000 has, but perhaps after I've used it for a while I'll grow to like it more.
