I have an hdmi to usb adapter between a roku and the pc. DV capture brings in a good image and sound level. However the only control I have is to start and stop the capture. Everything else, volume, pause... etc is faded. The result is okay but I get a random hiccup in the stream every 30 seconds or so. If I use Vegas Capture I get two mpg files, one for video and one for sound. I can place them on the time line, but I have to line them up manually. I guess there is a way to lock them together as I have to edit each separately and align them on the time line and this is a pain. Finally in relation to the hiccups, is there any adjustment to the way the stream is handled. The adapter is usb 3 into a usb 3 port.
