I'm still having the strobing/stuttering issue with the H.264 HD video but its not that bad so I haven't really got that involved with it because I don't want to completely screw it up. Like I've said before I'm a much bigger fan of mytheatre and will pretty much abandon DVBDream when the new version comes out. there are a few more HD channels than bev and since sky angel shut down on Echo 3 from what I've read is going to free up a few transponders for more channel's (spikeHD, speedHD, ect.) also I get my local HD channels where I'm at. I absolutely feel it was worth it. As far as the computer if your already pumping out bev HD you should have no problem. It may require a small amount more of processor and memory than bev channels but I haven't noticed much of a difference.
I've been using ANTepg for a while now but recently I've been running this new dvbepg along side of it to check it out. It's the one from the dvbdream site I found a web site that had the mytheatre files. My only problem with it is that you can't set fav groups just general favs and that list is getting a bit long. I do like the carbon fiber skin though.
