Location: Toronto, Canada
Cable Co: Rogers
Setup: I have a digital package from Rogers (not HD) but since they encrypt everything, I am only using the DVDR to record from the analog channels. My normal viewing is through the Rogers box, but when I want to record something, I use the DVDR. The DVDR is not in series with the Rogers box. I have two co-ax plugs and I use one for each component.
Problem: Sometimes the timer recordings will record the wrong channel. This has happened more then once. It happened tonight. During the recording, I checked the INFO and it listed the channel that it was recording (the wrong channel). However during the Timer Programming List, it listed the correct channel. The recording seemed to have about 1 second of the correct channel at the start, but this may be due to me just leaving the DVDR on that channel earlier in the day.
I have tried unplugging for several minutes, doing the RESET through the menu, and doing the SKIP-1-2-3 reset, but none of these have solved my problem.
First time I've heard this and can think of only two possibilkities:
1. Rogers is implementing Switched Digital Video (SDV), where channels are only delivered thru the cableco box and when a one of a local group's ("Node") tunes that channel. Only Rogers can tell you if they might be implementing SDV. If they are, you could be "picking off" channels as they're delivered through your Node to others, then detuned by them so you lose that channel??? This is just a SWAG, of course.
2. This is more likely and can be easily tested. I think your description of "two coax plugs" is a likely cause. To test this, set up the recommended way (
described here in detail), which is to put the 3575 1st on the coax, then coax out to the Rogers box, then coax out of the box to your TV. This allows you to watch a channel on the box while recording something else (analog channel) on your 3575. (Separate line connection from 3575 to TV, of course.)
There is NO reason for you to have separate coax inputs ("plugs") since the coax into the 3575 is a straight passthru of your Rogers digital signal... AND the 3575 passthru amplifies the signal slightly and you might get a 20% better TV pic, as some people have reported.
The 3575's amplified coax passthru is unique among current DVDRs so take full advantage of it!
With this in-line coax connection, your 3575 and cable box will be receiving THE SAME EXACT SIGNAL with no reflection or interference from your current separate "plugs." With the exact same AMPLIFIED signal, there should be no reason, other than SDV or a defective 3575 tuner, that could be causing a mysterious change in channel.
