Just tried running a System Test while a program was recording. The R15 came up with the message that the recording may be interrupted, I said OK. Test ran and came up with the test again option. But as soon as that came up I was presented with the "do you wish to continue recording" message as there was a show on my SL that was possibly interrupted. Options are are keep recording, stop and save, stop and delete. Press any one of those and the message goes away for 2-3 seconds and reappears. This continues....I guess forever. Programming loop? Pressing EXIT finally did get me out of that loop but it appears I lost the entire recording. The R15 didn't even save what it had recorded prior to starting the test.
