Got mine last night and just now got a chance to hook it up and try it out. I'm using a DVR+ as input to the modulator for testing. Seems to work fine, even on "Channel Master TV" Internet channels.
Good news: no audio glitches on an old iView, although as previously noted, the time is stuck at midnight (precluding timed recordings on said iView). However, the HDMI source does need to be set to PCM; otherwise there's no audio at all. Apparently the modulator isn't smart enough to pass through Dolby Digital. Too bad - that would've been an easy workaround for the audio glitches.
Edit: I don't know if this is common or just an iView oddity (there are a lot of those), but my iView shows it as channel 16-4, not 16-1. I haven't been able to get Windows Media Center to recognize the signal on either 16-1 or 16-4 though, even though my PC's tuners see a strong signal on RF 16. As CPalmer2K suggests in the next post, there may be something funky about its channel map. I've had similar WMC problems with broadcast stations that don't have their channel map configured correctly.
I made a test recording of a minute or so of RT on the iView. It is indeed 720p30. According to MediaInfo it's true 30 f/s, not 29.97. Audio is MPEG version 1 layer 2, not Dolby Digital. Those oddities may explain why some receivers experience audio glitches.
More good news: When tuned to RF 16, I can receive KERA on RF 14 and KTVT on RF 19 just fine, so the signal doesn't seem to spread too far from the selected channel. Its high signal level does seem to overload the iView's tuner enough to interfere with most LPTVs in my area, even ones far from RF 16, so it looks like I'll need to attenuate its output.
HDMI pass-through seems to work fine. The only wrinkle is, when the HDMI input is turned off, a floating "no signal" banner is sent not only to the RF output, but also to the HDMI output! Not a big deal but something to be aware of.
That's all for now - more to come though.
