My apologies, DarkRoastChris. I screwed up that first test with the Time Sleuth. I wasn’t able to actually test the Time Sleuth through the Denon with video processing off. It reports no signal like the OSSC with 480i through the Denon. The TS works fine with 480i when directly connected to my TV.
Is VIC something user configurable and/or a setting that profiles would support? I’m not familiar with that setting.
