I just got a Kworld KW-TV878RF-PRO with Conexant 878A chipset. I think I finally have everything setup properly. I can tune the cable channels and record shows. My problem starts a few minutes into the viewing/recording of shows. The audio appears to be cutting out after a few minutes. I have the line-in connected to my soundcard properly and as I said, I do have sound for a little while when I start. It doesn't matter what software I use, I still see the same problem. I used WinDVR (came with the card) and Vdub. If I go to the capture preferences and reselect the tuner the sound comes back on when I press OK. I did verify that the line-in was selected for audio source. Any help/suggestions would be appreciated! Thanks
