Yes, but the TPM could have "sealed" the keys the video is encrypted by, thus making you unable to decrypt your videos without the TPM enabled (and having verified your Tivo as running only "good" software).

where could TPM have these 'sealed' keys? they can't be in the hardware (especially if that can't be modified after manufacture)
if they are in the software they are accessable, if by no other means than by letting it get decoded and then reading the ram directly.

In the changeable part of internal memory. It's not like TPMs are _completely_ immutable.

They are not in software.
