Recordable DVD tuner - how high?

If yes, connect the cable there and see how high it would go. If it doesn't go as high as you like then my guess is that all other tuner will be the same.

My Pani goes at least to 600 as use it to get to music channel from my cable provider, but there is a catch, anything over 100, except the music is scrambled so eventhough my tuner can go to say 134, it makes no difference the picture is scrambled.

The best option is to patch your PVR/DVD Recorder to your cable box and get a recorder with an IR Blaster, this will change the cable box channel for you and then you use composite or S-video connections to get your video and l/r cables for sound.

One last option, my older pani does not have an IR Blaster, but my cable provider, in this case Comcast lets you set a "VCR" record flag throught the cable box, it is while you are looking at the TV Guide through the cable box, then pick the record option when the show is highlighted.

At the time and date of the show the cable box will change channels automatically and then all you need to do is set your recorder to start on that date and time and put in the record time / stop record however yours works and your source if on RF would channel 3 or 4 whatever your cable box is set on or your source would be like Input 1 or such if you are using composite/component cables to patch to your cable box.
