Yes, those succeed. So, that solves my problem, thank you. > If you can use the /dev/vbiN node as a work-around, please do. I will switch to doing that, and update the MythTV wiki appropriately. I assume that this is the correct invocation for any similar capture devices, not just the PVR-500 and family.

Sometimes shows don't send caption data, even the same program one week later. I happened to have two recordings in standard definition that had no captions, but one recorded last night did, as might be expected if MythTV already worked around it. Thank you for your time on this, Andy and Hans. I will update my scripts, and this will work perfectly for me. -- Christopher Neufeld Home page: http://www.cneufeld.ca/neufeld "Don't edit reality for the sake of simplicity" -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
