I can't wait to test this out. I got an HTPC, mainly used for satellite dvb, known as the CW3000HD.
If possible, I'd love to get my hands on the beta and see about getting kext's made for my pci and usb dvb/atsc devices and getting MythTV running with it.
Would look sweet as hell also, in 1080p glory.
Quick rundown of hardware:
Asus M2NPV-VM Mobo
AMD64 FX64 Processor
Geforce 6150 Video
Nforce Lan
A few other little things...
Would someone please put this on megashares instead of torrent when released? Megashares, you can upload a file w/out splitting it. Torrents take forever. Of course, ftp access is ideal
