I have all my DSP modes set to Trifield for 2ch Music and all 2ch Movie set to PLII Movie. I therefore assume that all my cable TV watching is with Trifield as are all my standard DVD's.
No, No, No !!
Most Cable TV these days is DD (5.1).
So my TV will default MulitChannel/Movie for TV to Cinema and that's what it shows 99% of the time. For 2 Channel/Movie I default to PL II Movie. It also has Music modes but Preamp doesn't really know if I'm watching a Movie or a Consert. So I default those for TV to Cimema and PL II. These are just defaults for that source.
On DVD/Blu-Ray I think there is meta data that can differentiate the SAME format data if it's sending a Movie or Music. I rarely depend on it. I use Phantoms to control it. I rarely use a Source for multiple purposes. TV/Blu-Ray is always Movie and 99.9% MultiChannel. Transporter is Music 100% of the time and may be 2-Channel or MultiChannel so everything defaults to Music Presets (for Movie or Music, 2-Channel or MultiChannel) on the transporter.
You should not use Trifield on the TV for much of anything. If that is displaying when watching TV, you have multiple setup issues IMHO, and possibly crappy cable service only sending 2-channel.
Roughly, these days
DVD should show Cinema
TV should show Cinema (PL II Movie on occasion depends on cable company)
Blu-Ray should show Cinema
2-Channel Music Server should show Trifield
