A few months ago my TSU9600 started having problems sending IR signals to my Scientific Atlanta VIP622 VCR (DISH box). Specifically any set of actions that sends multiple function commands to the VIP622 won't work. For example, I use the channel icons to get to HBO which requires me to send channel 300 as several commands, 3 + delay (.5) + 0 + delay (.5) + 0 + enter. It used to work fine but all of the sudden one day it stopped working for this device only. I can send multiple commands to my receiver, Blu-Ray etc. without any problem. What's strange is that I can send single commands to the VIP622 just fine. For example, I can get to HBO by pushing the 3 key followed by the 0 key twice and then the enter key.

I've deleted and recoded all the remote keys but the same problem occurs. If anyone has any ideas of has had the same problem I'd appreciate any feedback. Thanks.
