Jon, thank you so much for this! I have spent the last few days tearing my hair out over 2.6. Brad has had no problem, but I just couldn't get it to work. I looked at dma, ETBF issues, timing overruns. All the while your email stood silent. Brad went straight to using mplayer, but I was trying scan, reasoning that if scan didn't work, nothing would. But I don't think these apps enable DMX_CHECK_CRC. Just confirming : the crc checking in 2.6 relying on kernel /lib/crc32.c does NOT work. Workaround for the moment, don't use DMX_CHECK_CRC in your application. Jamie -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
