Note that your "random number" spells '09' in ASCII. I'd pick something above 32767; you're less likely to conflict with something present on the DVD.

My way is different from what lamster mentions.
I'm looking for a register that hasn't been set.

You're looking for a register that hasn't been set
via the navigation you used. I'm looking for one where we definitely don't care what value it has coming in, because the PGC modifies it without examining the current value. I think my way is better
if such a register exists (which of course might not be the case).
Another approach would be to analyze the register usage, and see what register's are only used in other areas of the DVD. But this probably goes beyond the scope of an introductory guide.
