Windows 7 - Channel fuzzy on one tuner, fine on the other?

Asked By Paul on 25-Jan-09 06:49 AM
Thanks in advance for any replies.

Two tuners
- analog
- dual analog/hd

Since buying a 2nd tuner for my MCE, my lowest channel (TVO) records
fuzzy. I've figured out that the default tuner (whichever one that is)
records this channel poorly.

In Live TV, if no recordings are happening & I move to this channel -
it's fine. If I'm recording a show & THEN move to this channel - it's
fuzzy. Unfortunately it seems the default tuner for recording isn't
the same default for live tv.

I'd be happy with input on ANY of these questions;
1. Why might this channel be fuzzy on one tuner only - any way to fix?
2. If I change the default tuner for recording - I assume this would
apply to all non-hd recordings - any way to make it apply to just this
channel? Even if not, how would this be done?

The quality of the encoding chips in all analog tuners is not the same in
all makes/models.
What are the makes/models of the 2 tuners?
Do you have recordings set to always record at best quality?  If not since
and since Live TV is always shown at Best quality this may be the reason
starting from Live is always better?

nce

Both are Hauppauge (one is the 1650 HD/Analog dual, the other is an
older analog).

Recording quality is set to best, and both cards do a GREAT job of
recording all stations except this one single channel, and only one
tuner does a poor job on that channel.

Is there a way to change the default tuner - or - a way to manually
tweak/adjust a single channel on a tuner with MCE?

Yes, but you cannot have the same tuner for both preferred viewing AND
preferred recording as the same tuner. If you wish to 'flip' the sources,
you can edit the Registry to do so (Google for 'more than 2 tuners in MCE'
to understand how you do it).

When watching the problem live channel TVO( do not know where it is or what
channel number it is) does it have any signal strength problems as indicated
by snowy video?

Thanks. I see what is meant by the default viewing/recording tuners.
One tuner has a bad channel on channel 2 (as I already mentioned), but
the other tuner has a problem with channel 14 - so if I switch them
I'd end up with a same problem, only on a different channel. Both
channel 2 & 14 are analog, coming in via cable.

I have only seen a signal strength meter in MCE for my OTA digital
channels - is there something for analog channels that come in via
cable? Instead of switching the viewing/recording tuner, is there a
way I can fine turn the reception of the analog cable channels?

That is very interesting, and you are a better Googler than I. I will
try this - when work/baby allow - and post the result.

I would prefer to *not* switch tuners (afraid of running that program
on my MCE) - which means I need to find out the analog broadcast
frequency of channel 2 (TVO) and not channel 14 for which the link you
proved actually gives the broadcast frequency. I have a sinking feel
finding the broadcast frequency for TVO will not be possible given
with my cable company (rogers is unresponsive at the best of times).
However - it must be close to 55.250 & I can take a few guesses on
either side to see if the reception improves.

Thanks again.
