So - my parent's system still won't view flash videos- Hulu, NBC, CBS, etc. They play for a few seconds and then freeze. OS X 10.4.11 iMac Intel. This is driving me more insane than any other Mac issue I can remember, because I only get over there so often and have left many times now without solving anything. List of things I've tried: •*Tested and problematic on multiple browsers •*Updated all software through software update •*Changed DNS settings to OpenDNS (and back again) • Uninstalled and reinstalled Flash 9 • Uninstalled Flash 9 and installed Flash 10 • Repaired permissions, in multiple combos of uninstalling/reinstalling • Tried another user account, same problems • Plugged in another computer to same internet connection - flash video works fine. •*Tested other (quicktime, etc) online vids, streaming keynotes - work fine. •*Other large downloadable content works fine UPDATED: had some time over thanksgiving to give this another go- tried some more stuff: •*Ran archive and install, did nothing •*Am now just realizing that due to the intermittency of the problem, the 'plugged another system into the same connection and it worked fine' statement is anecdotal only. •*Trashed all the network preferences, etc. and set the connection up from scratch •*Spent a long time with the sloths at the ISP, said 'everything looks fine!' • Blocked and unblocked port 1935 • Turned OS X firewall off completely •*ran and passed the hardware test from Techtool? (I think that's what it was called) Still no luck! Serenity now!
