According to the FAQ file in the videodev_2 branch, there are "early stepping" and "later stepping" versions of the 440BX. Just guessing, but maybe you have one of those early steppings? I can usually capture more than 20 minutes before I get the error. I assume you are using the original branch of the cvs driver. In case you've ever tried the zoran driver included in the kernel sources: did you have the same problem? Maybe you have never tried the version shipped with the (later 2.4) kernel? In that case, I would definitely recommend trying the videodev_2 branch. In my case, the kernel driver would give me an error syncing on a buffer, but I changed liblavrec.c from lavtools to exit cleanly when that occurs. I have written some python scripts to make capturing/encoding/ archiving easier, so in my recording script I just restart lavrec when it suddenly finishes and the total recording time hasn't been reached yet. So, in practice, I can capture almost reliably, but once in a while (quite often after more than your 20 minutes maximum, I have to add), I'm missing a few seconds because of the timer expired error. I can send you my scripts and explain where I've changed my liblavrec.c if it can help you. The normal cvs branch driver was worse, and I ended up with hanging lavrec processes. With the videodev_2 branch, I have the same results so far as with the kernel driver: occasional timer expired's, i.e. a workable but not perfect solution. > Oh yeah.

I'd definitely give it a shot, if you have only tried the regular cvs or the old 8.0 release so far. Hope it helps.
