SiliconDustHDHomeRun + BeyondTV with TWC 2-70 service (no digital boxes).
Everything was working great up until mid July. Since then, I've not been able to get any of the 98 and 99 TWC subchannels (which appear to be the SD digital feeds of most of the HD channels I can find, plus several we don't have as HD -- 12 and 19 from Cincinnati).
All the digital TVs in the house can still tune to the subchannels, and the SiliconDust sees the 98/99 subchannels about one out of every five scans, and when it does hit and include the channel in the digital tuner status, it comes up with nothing when I click the channel in the QuickView. BeyondTV can't tune the channels at all, I presume because the SiliconDust is having trouble. Non 98-99 subchannels appear to be all there, and operating nicely (Highway Patrol every morning at 5AM! on THS).
Anybody else run into the 98 and 99 TWC subchannels vanishing from a SiliconDust? Anybody have a thought of why this would be happening?
