[ExtractStream] 1.30

[David Gerdes]

Thanks Warren.

nc -n fixed that problem.

And I was using 1.50 tplayitsam, which explains the problem.
1.50a works fine.

So far, my test results look good. But now various tools are 
failing on these 1.3 streams. tyc crashes, patched vsplit 1.50
seems to work nicely, but mpgtx -i doesn't like the stream created.
(mpeg2dec seems happy with it tho)

splitstream which worked very well on 2.01 streams barfs on the 1.3 streams:

Almost all the chunks end up in the bad file.
I will 




The thing that convinced me to swap out Tivos was Tuesday's B5 recording
had several minutes of garbled video and audio, playing back untouched
on the Tivo. I don't know if my MFS is becoming corrupt, or if the
encoder is crapping out, or if the OS is not getting enough priority 
for some reason. I might rebuild 1.3 on it some time and see if the
problem goes away. 



Anyway, I am limping along successfully and should be able to report
soon on whether I am still having stream corruption problems.

1.3 appears to have a slower user interface than 2.01. I don't think
the hardware was much different between the 112 and 212 models.
