Gday all, I purchased my TiVo in Australia yesterday and got it setup ok. The only problem is I get sound dropout issues randomly. There is no particular channel it does this on (does it on all). Sometimes the sound dropouts are for minutes at a time, while it worked for many hours last night with no problem at all. I have it all connected via optical and the video (yellow) plug into my Yamaha receiver/amp. Anyone have ideas as to why this is occuring as it is more than a little annoying and makes it kind of unusable.
