I am experiencing this problem as well. In the watch portion of the tree, if you inbed a keypad on your first page channel logos execute perfectly so macros are possible in this manner but when attempting to link commands on the home page for activities such as "watch TV" it causes the remote to lock up. Interestingly, if I put a channel logo command on the home page and link it to the Sat keypad (three digit number plus enter with .2 sec delays) that seems to work fine, however, turning on and switching the system then jumping causes this lock up thing to happen! Very strange. If someone from Philips is reading this post, please contact me with info about a solution since I have several customers who wish to purchase the product and I will not sell it until I am confident about the resolution of this issue. I find it hard to believe that people are out there using this product and are not running into this same issue.
