I bought similar Kworld one a couple of years ago. Still working w/o problems. To run on Win XP you have to install crapy ArcSoft TotalMedia Software. I had version 3.0 but this one is probably 5 I tried both versions and got a lot of blue screens on TV recording. Playback and watching TV is OK'.
It is better to use PCI card - faster and quality of recording is better.

^ and it's double the price, though I agree that on a desktop system a PCIe card is the way to go if you can, with USB you can't even avoid lossy compression to get it over the USB2 bus... maybe someday decent USB3 tuners will arrive at similar prices.
That's BS....
The max data rate from an ATSC broadcast is 19.39 Mbit/s. USB 2.0 can do 480 Mbit/s. I have a similar TV stick (from ATI) and it has no trouble saving the original unmolested MPEG-2 stream of a 1080i HD broadcast straight to disk.

^ As I wrote, lossy compression. That's what MPEG2 is. That they do it for you ahead of time is not negating my point.
Further, I don't WANT to save an MPEG2 stream straight to disk, what a waste of disk space when we have much better codecs available today and the CPU horsepower to use them in realtime.
However, NO, USB2 can not do 480Mbits/s, that is the paper spec only and the real world performance depends on your system USB controller and bus contention. Normally USB2 peaks around 35MBytes/s but can't sustain over 28MB/s if you are using other USB devices on the same controller hub pair.
You're missing the point....
The ATSC broadcast is MPEG-2. And USB 2.0 is plenty fast enough to get that stream to your computer (no additional compression involved). Once it's on your computer you are free to reprocess it any way you like (g MPEG-4 to save space).
