    That's not several orders of magnitude. :)

    That and I am not sure whether h.264 material gets recoded when being sent to an S2, or not. I've never owned an S2.

    It would. S2s can't handle H.264 at all, so you would have to transcode them back to MPEG-2 to play them on the TiVo.

    OK, that prety much puts a period on the sentence. So unless one has a very fast server with very limited disk space, recoding to h.264 is really not advantageous if one has an S2. Jcthorne's recommendation is a solid one.

    Perhaps my terminology was wrong. I was thinking MTBF of a few thousand hours vs hundreds of thousands or millions was orders of magnetude, but perhaps I was using the term wrong. Still, a big difference in length of reliable service.

    I forgot about the S2 not accepting h.264 so yes, he really should not use it since they would be re-encoded on return to mpeg.

    Do you know if you can download the latest versions of VideoRedo if you buy an older version?

    What format/resolution are your videos? I transferred a 2 hr 10 min movie in best quality using my Series 2 and although it stalled at 99% it was still only 3.88 gb. So for my Season 2 I can fit most movies.

    Have no idea what batch or VAP is or COM functions.

    Maybe, but I read about people's hard drives failing all the time (especially external hd's which is what I will be using at least for the next few years). I've personally had hard drives go bad in a few computers.

    I never hear anyone talk about their own discs going bad unless they were not burned well to begin with. In my personal experience I've actually never had a music cd go bad on it's own going back nearly 20 years, never had a commercial or blank DVD go bad going back ~13 years, never had a VHS tape go bad going as far back as at least 1985 - outside of one having it's glue go bad where it holds the tape (easily fixed) and a few have minor problems with edge blunting. Also never had a video game on disc go bad going back to 1996. I'm not trying to argue, just giving my personal experience.

    I find disc media lasts even better than claims by manufacturers and you're likely to find a few go bad before they all do. I would not say optical media is dying because of it's structural quality and I do prefer to own hard copies rather than pay for digital versions where the license can be taken away at any time or unable to redownload.

    I would not necessarily care about viewing the shows transferred to my computer and transcoded to mpeg-2 or h.264 on my tivo again. If I could view them on an xbox, ps3, bluray player, dedicated media player that would be fine. My Tivo will probably die to the point where it's unfixable or not worth repairing before I start viewing most of the videos again anyways. I would prefer smallest file sizes at highest quality given the Tivo that I own.

    Are there any good threads/articles/tutorials on kmttg?

    You can always download the latest version of the the VideoReDo product you buy for free, but you would have to pay an upgrade fee to go from V3 to V4 or from Plus to TVSuite.

    VAP (Video Autoprocessor) is a free add-on available on their site. You can set it up to do cool stuff like monitor a folder and automatically process new files according to your workflow.

    COM functions are used by 3rd-party programs like VAP to access the guts of the program without bringing up the main user interface.

    VideoReDo and VAP work fine on Win7 64 bit systems. Running VRD as administrator just once after an upgrade or install is a recommended procedure for any Windows version.
    For VAP see link in my signature. Batch and COM are computerese that you don't really need to understand to use VAP or VRD. If you try VAP be sure to look at the documentation, VAP-readme.pdf, available at VAP link in my sig, and if you have problems or questions post on the VAP subforum of the VRD forums:

    Well, the odds of something can range from 0.0 to 1.0, and while the odds of a hard drive failure are considerably smaller than that of optica media, the difference would be at most 1 or 2 orders of magnitude, which is still a lot, and yes, there is no question hard drives generally last significantly longer.

    The MTBF for hard drives is not in the millions of hours. Typical MTBF for an optical disk may be 25,000 hours or so under normal conditions, and perhaps two or three times that under ideal conditions. A typical hard drive MTBF may be 100,000 hours, and again perhaps two to three times that at most. Unlike optical media, however, hard drives do not seem to be impacted by modest changes in ambient temperture or humidity. If the drive is kept near or below 70C, it will probably last just about as long as a drive kept at 30C. OTOH, a DVD kept at 70C will probably fail in a matter of days, if that. Under fairly well controlled normal conditions, though, a hard drive probably won't outlast a DVD by more than a factor of 4 or 5, at most, which is not even an order of magnitude. Three years vs. thirty years would be a very big difference, indeed, and that is only 1 order of magnitude. Three years vs. three hundred years would be two orders of magnitude, and I really don't think anyone would claim many hard drives would last three hundred years. "Several" orders of magnitude would be at least three thousand or thirty thousand years. Even if DVDs only last on average six months - and we all know they do better than that - four orders of magnitude would still be over 5000 years. I think not.
