Recently installed ATV flash - very nice piece of software! I have a large iTunes library and wanted everything unwatched to be stored locally, to avoid streaming issue (like, well, stuttering videi). So, I recently purchased and installed aTV Flash and a 500GB Seagate FreeAgent portable USB HDD.
With the exception of a small struggle to get the USB drive to show up, everything went without a hitch. After a couple of days, I have about 400BG of video ready and waiting.
I am experiencing occasional stuttering video playback with iTunes content. With purchased HD movies and purchased HD TV shows. I was able to watch an SD video that I created myself w/ Elgate Turbo HD 264 - that seemed to playback without any interruption.
The stuttering playback is as others have described on this forum: at different intervals, a video freeze of about 1/2 second occurs, followed by a brief period of sped-up video (as if it’s catching up), followed by normal playback. Repeat until annoyed. The interval for a particular video seems to be constant, but differs between different videos. I haven’t done thorough testing, so I can’t give repeatable specifics (I can do this, if it’s helpful).
I read through the forum and, as others have suggested, disabled Apple’s h.264 codec. To my surprise, that fixed the problem with an HD movie I was watching and I thought the problem was solved. Last night I watch an HD episode of Mad Men and the stuttering was back. I verified that that Apple h.264 codec was still disabled - it was. I also verified that I have updated/installed the latest versions of aTV Flash and Perian, et al.
Of course, I am suspect of the HDD - that is, aTV reads N bytes into its cache and before the aTV needs to read again, the drive spins down. Then, the aTV reads again, but the drive is slow to respond causing a delay in playback with a subsequent speed-up for a moment.
I don’t believe the Seagate FreeAgent drive’s ‘eco features’ are customizable, but I know other models support this (e.g. Western Digital’s MyBook). Before I go out and a.) buy another drive and b.) again, copy 1/2 TB of videos over the wireless network… can anyone tell me if this is a known problem, or is the stuttering playback another issue, entirely?
