I was just over @ NTCompatible.com and I saw that they have TVTool v6.5 for download... So I am assuming that TVTool has been updated but there seems to be no mention of an update @ the official page TVTool.de. So if you want to try it out hit Read More for your download.

On one last point NTCompatible have now opened up a dedicated site for Linux. Download TVTool v6.5
