[mythtv-users] live tv "jump program file buffer" error

[EJS]

>> when i bring up 'watch live TV' it works, untill i change the channel. 
>>> then i get the 'error opening jump program file buffer' message and

>I am having a similar problem except it doesn't seem to matter whether or not the channel has program listings. If the first channel is analog in Live TV then the only channels I can tune are analog - changing to any digital channel will throw the jump buffer error.  If the first channel is digital then I can tune both digital and analog channels. I agree its 100% repeatable.
