</div>How would MythTV know the difference between the channel<br>
tuned is currently not sending the any data from the specified<br>
program/serviceid (i.e. no data) vs. the capture card has failed<br>
silently with no indication of failure? If the capture card is failing<br>
to send data with no error messages than this is a driver issue<br>
(and MythTV does not claim to handle drivers that silently fail).<br>
Some drivers are probably better than others in detecting<br>
capture card failures (some do seem to do a handshake that<br>
if it stops, the driver produces errors; perhaps your driver<br>
could be enhanced to do something similar).<br>
<br>
I would recommend sending the error reports to the group<br>
(or individual) supporting your card. They may be able to<br>
assist, or work with you to provide appropriate debugging<br>
assistance. I hate to suggest it, but sometimes the<br>
Linux drivers are not as robust as those in other OSs<br>
(and sometimes they are more robust).<br>
