not so much lose any but we recorded cross country christmas on hallmark over the weekend. its a 2 hour movie, yet the h3 had it as 3hrs and 2 minutes. about an hour and 15 mins into it it froze and started over, yet i could rewind through the pause and error. its almost as if 2 pieces of movie were just stitched together. the recording even stopped before the movie finished. first time ive ever had anything like that happen, whether it be dish or directv. dunno if it was a hallmark issue or a dish one.
