A very early test version for the HD PVR is already out, if you searched you should have stumbled upon it.
Its still very early, and missing a lot of features, hence we did not announce it more publicly yet.
Deadlines are no option either, since this is an open source project and people do not get money to work on OBS in general. (The donations of course help jim to buy hardware, but thats about it)
If you want faster support of the HD PVR, get some programmers to help the OBS development :)
Hauppauge could have added support for their devices about 1 1/2 years ago, similar to Avermedia and Elgato for example. Actually, 99% of capture cards offer DirectShow drivers, only Roxio and Hauppauge are lacking these and then leave it to an Open Source Project to add support themselves.
