Upconversion problems with 1056

[angelo]

I don't know if anyone else is experience this, but my 1056 is doing
component up-conversation from a s-video direct-tv tivo/receiver. When
changing the channel the pq gets very distorted occasionally. It
usually, but not always, happens when I have been watching TV for a
while. If I go direct to the TV then the pq is crystal clear. I
originally thought that it was a bad Hard Drive in the direct-tv tivo,
so I had the unit replaced and the new one is also doing the same. I
also tried a regular (non tivo) direct-tv receiver and the same thing
happens. I am really frustrated because this was one of the selling
points for me when considering the 1056 over the 1055 due to claims of
better pq according to my dealer.

Any ideas of help would be greatly appreciated.

help us out here - a little more detail,

when you change channels and it gets a little more distorted, is it just for a second, or are you saying that if you watch one channel for an hour, it's fine, then switch and it gets worse and stays worse?

Also what kind of tv do you have?

Thanks for your reply.

It's for 2 to 5 seconds when a channel is switched. It never stays distorted for a long time.
The TV is a Sony Rear Projection KP-51HW40.

It sounds to me as though there is something strange going on with the video output when you change channels. The reason I think this is because it sounds like the receiver is having to "re-sink" to the video when you change channels but then sinks up again and everything is fine. I do not have any personal experience with TiVo but maybe others out there have one and have the same issue. Do you have this problem with a DVD player, or some other device, if you change inputs and then back or stop and restart movie, etc..?

So I tried with my DVD player and the picture never distorts.
I agree that it must be a re-sink issue.
I wonder if it because of the dual tuner??? Tivos have dual tuners so that you can watch TV on one channel while the other channel is being recorded.

The only catch is that it happened also on a non-tivo receiver with only one tuner.
