We're having this problem with our Series 2? single tuner TiVo and our Series2? dual tuner TiVo, but not on our Premiere. On all of them our season passes are being recorded correctly. On the two SD units only - but on both of them - TiVo suggestions may or may not be the programs they say they are (about a 50-50 chance). The channels it says it recorded, but did not, are correctly shown as in the channel list as channels we do receive. On one of the TiVos EVERY time it records the wrong channel the channel it actually records is the local CBS station. This is happening on the dual tuner. I know of no way to determine which tuner recorded which show, so I don't know if this affects only one of the tuners (the reason for the 50% chance of being correct)?? This problem surfaced with both TiVo units at the same time (a few weeks ago). Both are connected to cable boxes, with IR channel-changing. Those connections appear to be fine. I've rebooted both of the TiVos and both of the cable boxes, with no improvement. Any ideas? It sounds like a software change to me.
