I have exactly the same problem with a PVR-150 since upgrading to mythtv 0.26. In my case the PVR-150 is connected to a STB and LiveTV worked fine in 0.25 but in 0.26 I either see the "Please Wait" screen or a blank screen until I kill the frontend. I have also discovered that if I press the exit button on the remote then LiveTV will exit and return to the menu when the current program finishes. LiveTV is definitely being recorded, I just cannot view it.<div>
<br></div><div>In addition I see the same problem if I attempt to watch a recording (i.e. Media Library->Watch Recordings) before it has finished recording. Needless to say the WAF has hit an all-time low and I'm going to have to revert to 0.25 if I can't get this resolved soon.</div>
