Revision 3’s HD Nation did a nice review on this no-name Kworld ATSC 300U Plus TV HD 330 USB Tuner.
Looks like a good piece overall. Some posters on my Revo reviews have had good luck running it with little issues considering the Revo 3610 is technically under powered to run as a PVR. One poster does not use the included software, but rather uses WMC to control the recording of shows. Sounds optimistic! Think I’ll pick one up soon and do a test.
