> >>The way I am currently implementing this is to dump the station ID field
from datadirect into the xmltvid field in "channel". Does it make more
sense to do this a different way? Since there are already database changes
associated with this patch, I could easily add another field specifically
for stationid and populate it from datadirect.

>From a datadirect standpoint, there is the station id, which is an integer
(up to 12 digits). This uniquely identifies a specific broadcast station.
Then there is the channel, which is what you tune your TV to, this maps to a
station in a particular lineup. The channel "number" is actually 5 alpha
characters. This is always a number except for satellites, where there
could be alpha's and dashes.

I am mainly focusing on the internal grabber, which does not use the XMLTV
standards or IDs.
