Well, the more important point is that the HR10-250 isn't capable of receiving the stream from the new satellites, because it can't see the Ka/Ku bands that they use.
So even if you WERE willing to wait 2 days for it to transcode an episode of your favorite show, it couldn't receive it off the satellite in the first place.
Is that really the important point? I'm going to vote not, seeing as how Ka is just the frequency band, and frequencies are very easily converted.
Theoretically, you could connect a HR10 to a properly-aimed SlimLine and with the simple addition of a $20 converter, get the LNBF output back to L-band, which the HR10 definitely sees. Assuming the HR10 had the decoding capability (which IS the important point) and the guide mapping was done, the modulation is still DVB, so it would be very simple to make a HR10 (with M4 decoding) work on the new HD channels.
Getting the signal into the box at the proper frequency, demodulating it to M4, and writing it to/reading it from the HDD is the easy part. But you just won't find M4 decoding inside the HR10, so I think that might actually be the important point.
