If you are referring about watching two TV Channels the answer will be no. PIP is usually for watching two different sources at the same time, PC and TV, Video Input and TV. Bear in mind that some inputs might not have this feature available. For instance, the PC input might not allow you to use PIP. The only way that you might be able to see two TV channels is if your TV has two tuners and they implement PIP for both tuners. I do not think that there is such a TV in the UK at the moment.

I am not aware of any single digital tuner device that will allow you to do that. There are some old TV’s that were doing PIP with two channels but that was a different implementation. You are not even able to change the channel when recording with these TV’s. I have a HX923 and it does not allow me to change the channel when recording a program.

When using PIP you can use the input button to see which input are available in that frame and if you change to the other frame then you will also need to use input button to see what inputs are available. PIP is implementation dependant.

What I meant in my previous post is that the digital tuner will have a single function that’s all. There is no way you will be able to see two channels with a single digital tuner. If you have PIP activated in input A it create two frames where it will show input A and input B. With the left and right arrow in your remote you can select which of the two frames is the one active. In the active frame you need to use the select input button to see which other input are available to PIP.

Regarding subtitles, I think that subtitles are not supported whilst playing from USB but I am not sure. I think I read this in one of the posts. I never use that feature.
