Advertisements The problem with remapped local channels finally hit us. I'm trying to find how to use the slicer to upgrade S2 DTivos from 6.2 without losing all the recordings and settings. I suppose the most important settings are the season passes. Our units have TivoWebPlus 2.1 b3 110622 and I've used its backup function for SPs. I've made a paper print of the SPs so they can be reconstructed manually if necessary. DTV says the receiver needs to be connected to a phone line to get the 6.4a slice. Are there any configuration settings needed on a Zippered 6.2a to allow this? Are the slicer instructions at http://www.dvrplayground.com/article/13324/The-Slicer---Instructions-and-Release-Notes/ safe for my intended use or are there any modifications? The biggest issue is I'm trying to keep the existing recordings. Any help is appreciated.
