Fix 2 DTK bugs

Browse Source 
Bug 1: subcommand 1 of 0xE1 does not actually reset the current position; it just stops playback.  0xE2 returns the same value it would have before stopping playback (other than reporting that the stream is stopped).

Bug 2: subcommand 3 of 0xE2 was incorrectly dividing the length by 4; while this makes sense for positions (which are multiplied by 4 earlier to get a byte offset), it is not correct for lengths.
