I tested it while playing directly from /dev/dtv. Seeking forward causes 
it to pause for however many seconds it would have forwarded if it were 
reading from a file. Seeking backwards returns the message it did before:

    Cannot seek backward in linear streams!
    Seek failed

Other formats might not handle it as well so I'll add some code to skip 
the seeking when it's not reading from a file.
