Your right about the user manuals for  that TV not having much info on 
what codcs to use.

May I ask what the codecs of the source files/s are that you are 
interested in playing?

I also notice the TV can record to file from what you are watching. This 
may give a clue
as to one format it will support.

I might suggest one thing you could try to do is make a "dvd compliant" 
file and see if that
will play.

`mencoder -ovc lavc -oac lavc -of mpeg -mpegopts format=dvd:tsaf -vf 
scale=720:576,hardup -ofps 25 -srate 48000 -af lavcresample=48000 
-lavcopts 
vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9500:vbitrate=5100:keyint=15:mbd=2:trell:mv0:precmp=2:cmp=2:subcmp=3:vstrict=0:acodec=ac3:abitrate=224 
-o outfile.mpg <inputfile>`

The above command may work for you, try it on a small file and see what 
happens.
You could also tweak the bitrate (vbitrate for video and abitrate for 
audio) to whatever
makes you happy.
