I guess that probably mplayer in some version with -idx otion let you 
seek .rm files and with some other does not.
With my version 1.0rc1-3.4.2 (on winxp) it does not.

Now about flash video:

*getting info*: I use now media info 
"http://mediainfo.sourceforge.net/en", gpl witch gives you a good 
information.
for some other file formats is a nice tool gspot (on windows).
For some desperate case I play them in mplayer and I read the output in 
the console (you might use -v option)

*encode them*:
(example at 640x480, fps 15 or 30)

using mencoder:
mencoder yourfile.any -ofps 15 -o yourfile.flv -of lavf -lavfopts 
i_certify_that_my_video_stream_does_not_use_b_frames -nosound -ovc lavc 
-lavcopts 
vcodec=flv:vbitrate=1000:mbd=2:mv0:trell:v4mv:cbp:last_pred=3:predia=2:dia=2:vmax_b_frames=0:vb_strategy=1:precmp=2:cmp=2:subcmp=2:preme=2:qns=2 
-vop scale=640:480

using ffmpeg:
ffmpeg.exe" -i yourfile.any -b 1600 -r 30 -s 640x480 -hq -deinterlace 
-ab 56 -ar 22050 -ac 1  yourfile.flv

and after you can add some tag useful for streaming with flvtool2
flvtool2.exe u yourfile.flv

those files are seekable on my system.
