I'm not sure about the HD, but I'm definitely going to redo them. The HD stuff is a little tough on my system, and I think I'll get better results without adding anything I'm unfamiliar with to the mix.
TPM will probably take me 2 months to do, maybe less. Not that I'll be working on it all that time, but with the free time I have available that's probably what will happen. I'm leaving some wiggle room for the voiceovers, as I don't know how intense that will be.
