I have problems downloading Shows from my Premiere Elite (XL4). The download transfer won't complete on my new MacBook Pro, OS X 10.9. Think cTiVo people gave me a reason for my problem of incomplete TiVo Transfer transfers (and incomplete cTiVo transfers). Turns out that the problem Show had a glitch or burp when there was a momentary interruption of the audio/video (sound static and pixelation) at 7:38 into the recording. Guess if there is interruption in the TiVo recording, even for a second, I can forget about downloading the Show. cTiVo provided fast and outstanding support and their cTiVo app is great; it both downloads and converts the file format all in one.
