    In config--VideoRedo enable option to decrypt using VideoRedo.

    I don't believe there is any way for that qsfix to run on an encrypted file.

    VRD uses its qsfix to decrypt so no reason to run it separately.

    Thank you, I understand now, I was using VRD's QS Fix tool on the .Tivo file and then using kmttg to decrypt the new .Tivo file. Your saying if you use VRD to decrypt the .Tivo file it automatically runs the QS Fix tool before the actual decrypt. Thanks

    You misunderstand. It's not running qsfix then decrypting. It's decrypting on the fly as it reads the file using the TiVo DirectShow filter, which is why you need at least a partial install of TiVo Desktop.

    Yeah even though the resulting file is a .tivo it's still decrypted. The only part that remains encrypted after running it through QSF is the header where the metadata is stored. The actual video data is decrypted.

    o_O What I get is a .ts file with no metadata. I download in transport stream format and get a (presumably)encrypted .tivo file. Then qsfix runs against that file. Are you talking about what happens if you combine download & decrypt?

    There's an option in VideoRedo itself to "save as" where you have option to save as a .TiVo file. In that case you get what Dan describes - unencrypted video with header metadata.

    All my recordings made since I changed my Series 2 HD to Tivo Bolt have at least one section of dropouts/corruption after transferring to PC. I watch most shows from my Tivo on a laptop after conversion through VideoReDo because I travel a lot for work. The Series 2 HD recordings did not present any problems. When running VRD Quickfix it is not uncommon to see 2-3K frames removed. If a file contains a corruption and I try to use VRD to cut it, VRD will usually crash when transcoding the output file.

    My Series 2 HD worked better than my Bolt does.

    2-3K frames? That's too many. There are usually only 30-60 frames per second of video. So that means you're losing over a minute of content. Does the recording have an error when played on the TiVo or only when transferred to a PC?

    2 things.

    1. I've seen 30-40 seconds variance in the duration of multiple downloads of the same recording after qsfix.

    2. There's no such thing as a "Series 2 HD". It's either a Series 3 or it's not HD . And neither one supports TS downloads.
