I've looked at the HW MPEG2 encoders but MPEG2 seems to take up too much
room. I tried using the SW MPEG2 encoding in MythTV and within one day
my 160GB disk was filled. Even though I turned on automatic transcoding
to MPEG4, the recordings just seemed to get ahead of the transcoding.
Once the disk was full, it couldn't transcode any more. Do the HW
encoders produce smaller video files? I don't remember the exact file
size but I think a 2.5 hour program was something like 26GB! (640x480)
