does anyone have a problem with the CD-SR1 for the z1 where sometimes it doesn't work... like i guess its not getting the range all the time... but when i first got it, it was working perfectly... does anyone have any suggustions???

It's probaby the sunlight interfering with the ir transmission of the remote. Try blocking the sunlight from hitting the z1 and the remote if that works, then you've found our problem.
