Hey all, So I have had a TiVo hd with the tuning adapter for a couple of years now and have always been disappointed with the performance of the adapter but never enough to ditch the TiVo. Basically the problem I am having is the same as a lot of people in that the adapter constantly fails to tune channels especially HD ones. I have tried reboots, unplugs, etc and nothing seemed to work..until today. Basically I discovered that if I tune another tv with a cable box to the channel that will not get signal on the TiVo then change the TiVo back to that channel..voila...it works. I have repeated this about a dozen times on standard and hd channels. It would appear that either the TiVo software or the cisco tuning adapter is not able to request the sdv from the cable company head and that tuning the other tv to the channel successfully push the correct channel out to the TiVo/tuning adapter. I don't know if anyone else has discovered this or not and I know it's not really a god solution but maybe someone at TiVo can figure it our from this.
