It is not end of the story, I record lots of TV programs... travel, cooking,
historical, musical... They are still too large for storage, the HDTV
program is almost 6GB/hr. I re-compress (it is already H.264 compressed)
them with X264 to less than half the size. Actually I resize most of them to
1280x720/50Hz, it is less than 1/6 size and the quality is still amazing.
