I've traced the cause of the problem back to the PMS.conf parameter:
usecache = true
When usecache was set to true, The TrancodeExtentions parameter contained in the per-renderer configuration file (Toshiba.conf) was ignored for all video files in the same directory as the first video file played. However, the TranscodeExtensions parameter was honored when browsing to another directory and playing a second video file (as long as the other directory is not a sub-directory of the directory containing the first video file played).
When I set the usecache to false, transcoding on a per-render basis worked exactly as expected.

A bit of background - I recently bought one of the "new" Toshiba TL515 series televisions and it seems to be unable to display any mp4s that have a display aspect ratio of 2.35:1 (1920x816 DAR=2.35:1, PAR=1:1, SAR=1:1) - It doesn't display black bars at the top and bottom, instead it stretches the image horizontally. My PS3 displays the same mp4s correctly.
In my PMS.conf file I have:
mencoder_decode = -vf softskip,expand=::::1:16/9
forcetranscode =
notranscode =
I don't want to Force transcoding for all renderers. I only want to transcode mp4 files for the Toshiba TV so I created a really simple Toshiba.conf file with the following parameters:
RendererName=Toshiba TV
RendererIcon=toshiba.png
UserAgentSearch=BRCM DTV
Video=true
Audio=true
Image=true
MediaInfo=false
TranscodeExtensions=m4v,mp4
***************** RANT *****************
Now for a little rant about my "new" Toshiba TL515 which I recently bought directly from Toshiba yet it has a manufacturing date of May 2011. I bought it so that I could use it as a stand alone renderer. It was a bad decision because I've found that the TL515 is not capable of properly rendering many of the mp4 videos on my media server without using a transcoded stream from PMS. It's great that PMS can transcode video but it would be far better if the TL515 could render the videos correctly in the first place. I have a PS3, a WDTV, AcePlayer for iPad & iPhone - They can all play the mp4s natively at the correct aspect ratio without transcoding so I'm surprised that the Toshiba TL515 can not.
The Toshiba TL515 doesn't know what to do with anamorphic videos. It seems to only be able to properly render videos that have either a native 4:3 aspect ratio eg: width=512 pixels, height=384 pixels or native 16:9 aspect ratio eg: width=640 pixels, height=360 pixels.
Other dislikes about the Toshiba TL515:
- Overpriced compared to a non-DLNA compatible TV
- It takes a long time to start after pressing the power button.
- It has stopped responding on a number of occasions and I've been forced to restart it by unplugging the power cable.
- The remote is gimmicky.
- The last firmware update was October 2011.
