Thanks everyone! I do love the TIVO interface so any D* unit with Tivo is a plus in my book. I agree with the strengths of the dual tuners, info buffer, 30 second skip etc.
However, I should have been more clear in my original post. I don't subscribe to D* HDTV but I do have a Panasonic HDTV so I could benefit from the OTA HD stuff with the HR10-250. I purchased both a HR10-250 and a SD-DVR40 yesterday at Compusa on clearance and I'm deciding which one to keep. I could upgrade the drive size on the sd-dvr40.
What's the real benefit to me to keep the HR10-250 vs. the sd-DVR40? Is it worth the extra money? I got the SD-dvr40 for $19.99.
thanks
