I been looking all over the net for a good review for the Miglia TVMiniHD and couldnt find a decent one. So I just decided to take the plunge and purchase one for my 2.0 Ghz Macbook. Whats the results? Great HD and picture quality with no hiccups whatsoever. Here are some pics:

I have it hooked up to my cable line and it picks up also all other channels along with the HD channels. It also acts as a PVR and there is no pauses or stutters when pausing live TV/HD, even while multitasking...but then again i have 2MB of ram in my Macbook

. It also allows for scheduled recording and the results are fantastic!
The only downside is that the included antenna didnt pick up too many channels and when it did, it stuttered quite a bit. So your best bet is to hook it up to a cable line and let it pick up unencrypted cable (QAM) signals.
It ran me about $180 shipped. If you have a Core Duo Intel Mac and want to get some HD programming on it, this is a pretty good deal!
