[mythtv] Re: Another problem with nuvexport and possible fix...

[George Styles]

Hi,

I have now recorded a couple of shows and put the .nuvs up on my web site.
The can be found at
http://files.ripnet.co.uk

There is a readme.txt file describing where they came from, but basically 
there is
1. A BBC 1 recording, which tcprobes OK, and encodes with only a little 
'green blocking' with the -mpeg2 flag removed.

2. A ftn recording, which cannot even be tcprobed. I think if it was longer, 
and my tcprobe patch was applied it would work from my eariler experiemnts.

cheers

g
