I've got an S3, had it for about 9 months. Just upgraded to an MX-1 and a750gig DB35 drive about 3-4 weeks ago. All went perfectly. The last 5 days I've a problem with TiVo twice losing all my channels. Hard and soft rebooting would not bring them back, I had to remove both cable cards and reinstall them one at a time. My Sony SXRD with cable card has no problems at all, never looses channels. Coincidence that it's happening after the upgrade? Any thoughts are much appreciated.
