<div dir="ltr"><p>I recently started getting an error "The file for this recording is empty" when I tried to watch a recorded program. I'm running Mythbuntu on an AMD Athlon XP 2500 with 1.5 GB ram. I'm capturing video on a Hauppauge HVR-1600. I had to recompile my the Hauppauge driver recently when the kernel was updated. I recorded a few shows successfully after recompiling, so I don't believe driver is a problem.<br>
<br>I pasted a good portion of my mythbackend.log file. I've seen some suggestions not to paste too much, but I'm not sure what is important and what is not. I apologize if it is a bit long but I didn't want to omit something the I thought looked benign and was a key piece of info.</p>
<p>I also noticed that it seems like things start working again if I reboot in the morning. It appears like this could be related to the timing of running mythfilldatabase at around 6:00 am. It seems like I'm good up until that point and then I need to reboot after.</p>
<p>I appreciate any help you can give.<br> <br>Thanks,<br>Greg</p>
