We'd recommend connecting the Cable Box and the Blu-Ray player separately to the television, although there may be a reason for this kind of configuration.

If you'd like to post back with more details, we'd be happy to look into it and assist however we can. Thanks for your interest in Samsung televisions.

cassim,

The BD-F7500 has 7.1 analog outputs for audio systems that will support it.

Additionally, there is an additional HDMI output option on the player.

All of the other great features - 4K upscaling, Smart Hub and 3D are included on both models.

Thanks for your interest in Samsung products.

It doesn't appear at this time that the BD-F6700 supports the Hulu Plus App.

Here is a list of Samsung models that do support Hulu Plus:

Jim,

The Smart App offers options for streaming movies and music content. While specific stations may not have an App available, we cannot guarantee streaming content from websites through the browser. While most site content will load to view, we cannot guarantee compatibility with all websites, particularly when it comes to streaming content.

Happy Holidays!

There's a significant difference if you connect it to a 4K television, since the BD-F7500 is designed to do 4K upscaling.

If you have a 1080p television, you won't see a significant upgrade. But if you ever plan on purchasing a 4K television, you would be ready with this Blu-Ray player.

The BD-F7500 also has 2 HDMI output ports, and the BD-F6700 has one.

We don't advertise either processor or other internal components, so unfortunately, we can't address that question.

Thanks for your interest in Samsung Blu-Ray players.

Brian,

Yes, the BD-F6700 is HDMI-CEC (Anynet+) capable, making it easy to use with other Samsung products.

Thanks for your interest in Samsung products.

This model, the BD-F6700 is a 3-D Blu-Ray player.

As for the BD-E5700, that model did not have 3-D as a feature.

Thanks for your interest in Samsung Blu-Ray players.
