I have the HiMedia Q5. The quality of the internet streaming depends on your connection speed, the provider as well as the content itself. The Q5 has built in custom apps for streaming over 200 live TV channels from China and also movies and TV shows from PPS, YouKu and other providers via the HiTV app.

The TV channels are in SD and some of the content from the HiTV app are available in HD. However, the download speed is inconsistent. On some days I can watch in HD 720p while on other days, I cannot even stream 240p. I have a 10 mbps connection and I connect the Q5 using wired LAN connection. Streaming HD content from YouTube though is not a problem. When I am streaming HD content, the quality is very good.

I have a full review of the HiMedia Q5 at http://www.squidoo.com/himedia-q5-android-...a-player-review

Actually it is the GPU that is doing all the heavy lifting for the video decoding. When browsing, the performance is about the same as browsing on a dual core smartphone. Don't expect performance similar to a PC.
