I let my TIVO be updated normally. I am not using the "save room" option. I
have two 60 gig drives in the system. This reording is in "best" quality.

I'm not certani how to find out where the error occurs other than trial and
error. is there a better way? I'll gladly send you a piece of the ty stream,
or all of it if you're really willing to handle it.

Email me privately if you need to at: mpatterson@a... and let me know
what you want and where.

If it helps the tools work better i'll look at a few more "x10 spycam" ads.
