    Somone with both a THR22-100 and an HR22-100 should swap hard drives and see what happens

    Why? Neither box will work properly. What do you think will happen?

    Id image they would just reformat eachother as the OS is stored on motherboard and not the hard drive. That is why its so easy to swap out hard drives on the HR series.

    Would be more clear to ask - what files system THR22 is using ?
    We know HR22 - EXT3+XFS.

    He probably thinks the Tivo software is on the THR22 hard drive and swapping it into an HR22 will turn it into a Tivo:)

    But is tivo just on the MB? It didn't used to be on there other machines. You could possibly render your unit completely useless, and since you'd be on a lease, you'd be really screwed for opening it up.

    Of course first I have to point out that 100% of TiVo devices in the field, and close to 100% of HR22 devices, are leased. Opening the case is a violation of your customer agreement.

    If you did do a drive swap the only thing that would happen is that you would lose the programming on both drives. So it's not worth bothering.

    The middleware (the software that gives the DVR its personality) does not reside on the hard drive.

    Ah, well that answers that question. I had a feeling TiVo had to change that too, probably another reason it took them so long to port it.

    Neither company wants their units to be hacked like the old ones.

    That is the first time I have heard that mentioned.....but a "system on a chip" approach very well could be what took this so long to get here.....stand alone TiVo boxes never went that way did they??

    System on a chip (SOC) refers to the hardware in the box. Both TiVo and DTV boxes have had Broadcom SOC chip sets in them for a while now. The SOC in the THR22 is reported to be very similar to the one in the standalone TiVo HD that the software comes from. So no, that was not the source of delays.
