I use Tivo Desktop to move movies from a series 2 tivo to my laptop and have not really had any problems doing it. Over the past couple weeks, however, transfers proceed up to 2048mb and then halt with error "The recording started transferring but has been interrupted..." Half hour shows, ie smaller files, transfer without problem. The only thing I know I have changed in the past month is moving from Mcaffee to Kaspersky for my virus protection. I noted some comments about firewalls infringing on transfers in other threads here, so I disabled the Kaspersky firewall completely, but that didn't help. Anything magical about 2048mb?
