I have an HDMI splitter hooked up to my tv for my HR20-100 and my blueray. Last night I had channel 498. This morning it was gone. Just a gray sceen. Could the splitter be causing it or D* problem?
I've read that 498 is popping in and out. How about 9300 or 9301?
If you have a decent physical HDMI switch it shouldn't cause a problem... Only if you were trying to split the output to multiple TVs could you lose signal strength due to a loss of signal.
