A few years back I proposed the original change to the budget driver to switch from 2 odd/even buffers to a single one because I was seeing some data corruption when using 2 buffers. At the time I found that the hardware had issues when switching between the 2 buffers and would often indicate the wrong one during the switchover. Maybe something like the patch the linked email is worth trying again? http://www.linuxtv.org/mailinglists/linux-dvb/2003/08-2003/msg00467.html The patch was discarded when I later found that just using a single buffer was a simpler solution. > - Hartmut > > > > _______________________________________________ > linux-dvb mailing list > [email protected] > http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb _______________________________________________ linux-dvb mailing list [email protected] http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
