Amazing though how your whole afternoon can get screwed up by a lack of 2 inches of heat shrink tubing. I had to run around Manhattan because it turns up I ran out and didn't realize it.
It's all working now. Some observations:
- My Pinnacle PCTV HD Pro 801e consumes about 120ma at idle, and goes to 320 at digital capture.
- The power consumption doesn't fall back to 120ma after I stop capture (suggesting the device is not being put back to sleep properly)
- My Pinnacle PCTV HD Pro using em28xx consume 520ma both at idle and at capture. That's not good and suggests I might have both the lgdt3303 demodulator and the tvp5150 enabled at the same time.
