sorry to double post
after a few hours of research (and not enough work)
it seems the hd pvr is a downgrade from the roxio in usability and support. and only an upgrade in terms of video quality
to get audio working i have seen videos and screenshots of elaborate setups using external mixers, spliced cables 2.0 channel audio only, where with roxio it was as easy as buying virtual audio cable
to get streaming working i have seen vids where people have captured thier desktop (specificly the preview window of the software included) which clearly is not going to be true hd and will lag behind on sound)
i have seen tutorials on how to record audio from a mic and video at the same time by using two apps and being real quick at starting both (i kid you not some believed this was acceptable! perhaps i have been spoilt with the roxio)
but i did see this in the faq
so how can a non developer set this up?Can I push video encoded with Colossus or HD PVR through VLC?
Yes. If you are a developer, you can bring H.264 encoded video in from either Colossus or HD PVR into VLC so it can be streamed out from your PC. Microsoft provides a sample network transmit/receive filter set in their DirectX SDK.
Here is the way this works:
The HDPVR encoder filter produces transport packets. If you (the developer) create a small 'network push' filter that can receive the transport packets in the directshow graph, then forward them to a udp network address and port (for example udp://192.168.1.1:1234), then VLC is capable of receiving and rendering them.
Start VLC from the command line with: vlc udp://192.168.1.1:1234
surely if this exists there has to be apps that will use it.
i feel like i just got rid of a mini to buy a ferri only to get shipped a skoda
