It is not supposed to thumbnail every ten minutes or when you hit the edit button! What that does is insert a chapter mark for navigating through the dvd instead of hitting the fast forward or rewind button. Nowhere in the manual does it say it inserts a thumbnail at intervals or when you hit the edit button.
in mrlewp's post he had
"You must now STOP the recorder....in order to create a new thumbnail for next chapter, in same manner above. Re-pausing will not allow you to create the new thumbnail.
Hope this is clear....it does the job."
Recording off the satellite and not being able to control it you will only have 1 thumbnal at the beginning of the recording but you will have chapter marks (without thumbnails) to advance back and forth through the recording at the interval you did in the setup or whenever you hit the edit button.
Du - oh I don't think you did read the manual and the responses to your post. You started the sarcasm not me. Again read the manual and of course responses to your posts. If you don't understand ask another question but without the sarcasm.
Edit - the 5005 records in sessions, when you hit record and when you hit stop or when a timed recording starts and stops = a session. On page 25 of my manulal it shows 6 thumbnails and then says pick a session. Have you ever made more than 1 session on a dvd to see the difference?
