I'm a TWC customer using the SA 8300HD DVR unit. I'm running the HDMI output directly to my TV (Sony KDS-55A2020). We have a three way splitter coming off the TWC digital cable signal, one going to our other TV in the bedroom, one going to the main Sony TV, and one feed into the 8300HD. We have a constant problem with the TV losing channel lock (picture turns to snow)- not always but randomly and frequently - whenever we scroll up or down channels using the SA 8300 remote. (fyi - we're never watching both TV's at once) . The only way to correct this is to scroll through the inputs on the Sony remote to re-establish channel lock. If anyone else has encountered this and has any recommendations, I'd appreciate hearing from you.
