by clean I meant uncorrupted - not degraded during extraction

from tridges readme
use vplay to "play" with that fsid to a file or device

use vplayer to play files remotely
vplay default usage msg
/var# vplay
optind=1 argc=1

vplay <fsid> <vidfile>
OR vplay -p <fsid>

options:
-s <start> starting chunk
-c <count> number of chunks to play
-v be verbose

use the 2nd form for direct playback on a TiVo

vplay takes a fsid for stream files. See liststreams
so a little experimenting will generate something like this

vplay 1400984 temp1.ty
mfs_export 1400984 temp2.ty
mfs_stream 1400984 temp3.ty

/var# ll *ty
-rw-r--r-- 1 0 0 7208960 Oct 18 07:43 temp1.ty
-rw-r--r-- 1 0 0 7340032 Oct 18 07:43 temp2.ty
-rw-r--r-- 1 0 0 7340032 Oct 18 07:43 temp3.ty

vplay grabs just video, export & stream get the entire fsid
