Over the last several weeks have been experiencing problems with my dct3416 pvr. Issues include picture and sound dropping at random. Seems to require changing channel to get pictures back. Sometimes happens multiple times in same show. Also seeing pixilation and pauses in recordings. Does not change anything if exit recording and return. Issues occur at same place in recordings. Unit has shaw expander attached. Have tried power cycle reset process as well as reseating all cable connections. No improvement. I have seen this issue on several posts, however if issue has been resolved it seems to be by pm. It would be helpful if the resolutions would be posted in the discussion. PM kind of defeats the purpose. Any suggestions on a resolution?
