10GB is within spitting distance of the capacity of a dual-layer disc. If that<br>
10GB includes commercials, then after editing them out, it would probably fit<br>
on a dual-layer disc. OTOH, dual-layer discs are likely to be less archival<br>
than single-layer discs, so you might need to compress it down or split it<br>
across two discs. Compressing it is fairly easy with MythArchive, although<br>
it'll take the system a while (possibly hours) to churn on that file. (A tip:<br>
Don't burn directly to DVD; create a file and then burn that manually. That<br>
way you can check the file first to be sure it's OK.)<br>
<br>
If you want to split an existing file into parts, it's possible, but you've<br>
got to juggle files. First, copy the original file to a backup location. (You<br>
may need to figure out which one it is in the recordings directory.) Then use<br>
MythTV's editing features to lop off part of the file -- say, the second half<br>
if you want to break the file in two. If the file's already in MPEG-2 format,<br>
your best bet is to select lossless transcoding options; that's quick and<br>
results in no loss of quality. When you're done, you should have a file<br>
that's roughly half (or whatever) the original file's size. Copy that to a<br>
video directory and move or copy the original backup file back in its place.<br>
Select another lossless transcode and MythTV will recognize the original<br>
recording in its full size. You can then repeat the process, but this time<br>
lop off the part that you preserved the first time around. You'll now have<br>
two (or more) files, each sized to fit your DVD. Use MythArchive to burn them<br>
without re-encoding them. Of course, there are lots of variants of this<br>
procedure that involve different types of transcoding or other details. You<br>
could also use non-MythTV tools to do this sort of thing.<br>
