Do you mean "overlap"?

Note that we provide a few "TxDb" packages that contain pre-computed
TranscriptDb objects for a few organisms and tracks:
http://bioconductor.org/packages/release/BiocViews.html#___Transcri
ptDb
There is one for hg19/knownGene: the TxDb.Hsapiens.UCSC.hg19.knownGene
package.

This warning is wrong. It's actually easy to check that all the CDS
have a cumulative length that is a multiple of 3:

Seems to be a regression introduced in BioC 2.14. Someone in Seattle
will work on a fix and we will notify the list when the fix is
available.
Otherwise, assuming the code in charge of issuing the warning is
working properly, you can get a legitimate warning like this for
some combination of UCSC organism/track (but AFAIK never for the
knownGene track). If all you want to do is find/count overlaps between
some rna seq reads and known genes, then you probably don't care about
CDS at all.
