Working in bytes doesn't really make sense with transport streams.
They consist of packets that are 188 bytes so you should use bs=188. If 
you don't you may even confuse some players (not mplayer).

The seek and count values are in blocks so depending on what bs= you use 
you have to divide by this. Default is IIRC 512 bytes.

It may still be nicer to use other software if you can as streams 
contain flags which indicate random access points and cutting to these 
is preferable.
