#8 tivodecode-0.3pre5 with TS support

[Anonymous]

I've been using tivodecode-0.3pre3 for some time with TS files with a lot of success.

I can't take credit for this update, reneg, posted it here: http://www.tivocommunity.com/tivo-vb/showthread.php?t=446048

I thought it would be good to share the update that allows tdcat to work with tivo files that are not encrypted.

I've also updated the CHANGELOG to reflect changes made to previous version that were not included in the CHANGELOG.
