Experiencing this with problem with both HR24 and HR21 using MRV: When I select a program recorded on HR34 in Program List, no menu appears on far left (Play, Delete, etc.)... instead have black box where menu should be. Rebooted both HR24 and HR21, still continues. Reboot of HR34 needed to restore the menu. Programs recorded on HR21 and HR24 were fine, only issue was with programs recorded on HR34.
