Although a bit late, I realized that my Philips TV is not a high quality TV via DLNA, because it is not DMR DLNA certified. Only it is certified DMP.
DMR certified y W7 certified, are a logo stands more?. No, unfortunately for those who have recently paid a high-end Philips TV in very high cost.

In a nutshell:
DMR (Digital Media Renderers) is the device's ability to do PUSH. It's smart. Understand the possibilities that the Media Server (DMS) offers and is able to intelligently select the best playback high definition suited to their own technical capabilities. Intelligently communicates with the Media Server, more intelligent as Media Server and DMR will get better results.
DMP (Digital Media Player) is the device's ability to do PULL. Not smart. Only able to access files stored on the Media Server and play only those files whose multimedia codecs that are supported natively by the player from the TV.

Our Philips TV via DLNA is not smart because it is not DMR certified and it is not fully integrated with W7 did not meet the requirements to be W7-Play-To certified, or any other Media Server DLNA 1.5 certified with Play-To feature..

For more information, can consult the following simple and interesting article:

Philips TV and Toshiba TV are DLNA 1.5 certified, but:
Toshiba TV is a DMP and DMR certified.
Philips TV only is a DMP.
To check can access and select "Play To" Receiver in features, and Philips in Manufacturer, shows no Philips TV with that feature. If we select only Manufacturer Philips and after we select top model 58PFL9955 TV, shows Product Type: Digital Media Player (DMP) and Certification Date: 4/27/2010. If we select any Toshiba TV model with "Play To" Receiver in features, shows Product Type: Digital Media Player (DMP) Digital Media Renderer (DMR).

Toshiba TV is better than Philips TV via DLNA.

That Philips TV is not DMR certified:
Is the reason that problems occur FastForward / FastBackrward in certain cases?.
Is the reason of occurrence of lack of synchronization between image and sound in certain cases?.
Jumping on the playback speed in certain cases?.
Any other possible problems that cause poor also via DLNA?
I guess they owe more to the lack of codec support more correct, but I doubt whether it would require not resolve, in part, such problems obtaining certified DLNA DMR y W7 certified.
What seems certain is that the problems of poor reproduction, when using a Media Server with the feature Play-To certified (eg W7) that performs transcoding when the codec is not supported natively by the Philips TV, must that Philips TV is not DMR certified.
What is clear is that there are other devices on the market DMR cetified which there are no such problems.

However, for those who possess a Philips TV device, the most important question would be:
Are Philips ready for DMR certified?.
Are Philips doing something for DMR certified?.
In the event that Philips obtain DMR certified in the future, will update the firmware of the current TV-DMP to be DMR also?.

@ Philips, can you give any official information on this matter, however slight?.
Thanks in advance.
