Hi Preston,<br>I haven't yet gone to firewire recording (I need to upgrade to a more recent Fedora to make that happen), but I have tested out firewire recording with comcast and the RNG110 cable box - it does seem to work. Can you provide some more general information about which cable box you have, and the exact behavior of the dropouts? Is it just a bad packet or two, or is it several seconds of bad data? Anything in the kernel logs to indicate a firewire problem? Some cable boxes have the firewire port, but handle firewire output very poorly.<br>

Comcast recently turned on encryption for the bulk of their channels,<br>
blocking QAM tuners, so my options now are to use the analog output of<br>
the cable box with my PVR-250 or to use Firewire. They aren't<br>
encrypting Firewire for basic cable channels, so that seems like the<br>
best option. I've gotten Firewire recording to work.<br>
<br>
Unfortunately, when I record with Firewire, I get some digital<br>
drop-outs. I didn't get them with QAM, so it shouldn't be a<br>
signal-strength issue.<br>
<br>
Any suggestions for figuring out the problem and fixing it? I'm<br>
currently running Linux 2.6.32.7 with the new Firewire driver, but<br>
wouldn't mind upgrading if that would help.<br>
