Hi there - this is my first post! Recently I completed quite a long movie of a recent overseas holiday shot in 16:9 HD on a Panasonic TM-300 camera, edited firstly in iMovie 8 and completed in iMovie 9. I live in a PAL country so my native frame rate is 25fps. I want to show my movie in HD so that rules out a standard DVD (although I have made one successfully "for safety"!) I decided not to get a BluRay recorder/player yet until the prices come down a bit. So I decided to upload my movie to my TiVo (which has an external 1 TByte drive giving me lots of storage space). Using iMovie 9 I "shared" my movie using "Export Movie..." selecting the highest reset resolution namely HD 1080P. This produced a .mov which plays smoothly both on a Mac and on a Windows XP computer. But when I send the movie to my HD TiVo using "TiVo Desktop", the resulting movie while good is not as "smooth" as on the computer. Specifically, on very slow moving scenes all looks well; but on rapid movement of the subject or on pans and zooms the picture "staggers". If I use the TiVo's ability to play in slow motion, I see even movement between frames for 4 frames but the next frame is a repeat of the fourth frame in a sequence that runs "1, 2, 3, 4, 4, 1, 2, 3, 4, 4" etc. Again when the original .mov is examined on either Mac or Windows the movement does not show this "stagger"; instead it looks like "1, 2, 3, 4, 1, 2, 3, 4, etc. [I am using "1, 2, 3, 4," merely as a way to describe what can be seen; it has no technical meaning apart from that - ie it bears no relation to the PAL field sequence]. 1. My first question then is has anyone else seen an effect such as this when transferring a movie from a computer to a PVR such as Tivo? 2. Can you make any suggestions as to appropriate codec settings for storage on TiVo preserving HD quality playback?
