I recently picked up a series 2 dtivo, which has been upgraded, seems to work fine, except the parental controls were set, how do I get around them, I don't care about losing the programming on there, but do mind losing the upgrade, it has a 120G HD now, so I presume letting it call in and so forth would be 'bad'. (don't recall what software he used, but says it doesn't need to call as it is set up now)
