These are my settings and it does what I think you're after. It starts at video 1 and each video starts at the beginning as you change the channel.

tvType=TinyTV2
fwVersion="1.2.4"
channel=1
volume=6
alphabetize=true
loopVideo=true
liveVideo=false
static=true
showChannel=true
showVolume=true
powerOffSecs=300
randStartTime=false
randStartChan=false
roundedCorners=true

I wanted to curate the flow of the videos so I name the files like:

0100_vidname
0200_vidname

etc. That way they'll load in the order you want and you can always slot more in.
