Adams, Thanks
That's right, they told me when I signed up for the service it was just rolled out about 5-6 weeks ago. As for format, I just know it's about 4.4 gig for a 2 hour high def recording of a Fogerty concert per the system as it was copying to the drive it formatted, a WD Book 500 gig drive. Likely a form of mpeg. As for disk itself, DVR wouldn't accept the NTFS layout already on drive. It immediately asked to format for use with DVR. It isn't FAT 16 or 32 either as XP doesn't recognize the format when I used computer management tool. Just said unknown. I don't have any other tool that may tell what it is. Be my luck it's proprietary to Dish, or Carver, is that who makes the 722? Anyway, thanks for taking time to respond.
