Dangit...I spent the better part of 2 days f'ing around with my STB, Vista MCE, MyTray, CapDVHS and finally SageTV only to stumble on this thread.
What has Shaw done to us, and is it permament?
FWiW, I've used graphedit to capture some raw .ts streams...Windows has no clue what it is or how to decode it. The bitstream is mucked up (either encoded or downright destroyed) either before the firewire port, or at it. Since the STB seems to deal with it fine, and _some_ stations like HDNET work, I suspect it's encoded or watermarked in such a way that the STB is ignorant of the modification, yet Windows can't deal with it.
Any luck on a Mac?
If this doesn't get resolved, this may be it for firewire on Shaw.
(Seriously - Merry Christmas!)
