i was told by numerous reps that even though tivo is being supported through 2010, that the HD signals that are being added this year will all be mpeg4 and they will transfer the current HD to mpeg4 also. this means that a series 3 will get local HD, but no satellite HD could be recorded. an hr10-250 would be crippled in the same way.
i am in a rock and a hard place. i cannot get local HD OTA. the hr20 has some definite advantages over the hr10 and only minor drawbacks. it seems to me that directv let the directivo units fall so far behind the standalone units so when they released the hr20 people would think it was an upgrade... when really, if the directivo would have progressed the same as the stand alone, the hr20 would have been a step back.
