I reported this 'feature' on the ATrpms list. I'm told it's unlikely
to be a packaging issue. It would be nice to have it disappear.
Subtitles are accessible on recordings from DVB-T, but are lost after a
'lossless' transcode (done to make a permanent recording using a cutlist).
I'm running the latest version of Mythtv for FC5 downloaded today (27
Sept 2006) from the ATrpms repo. The main package is
mythtv-0.20-139.fc5.at.i386.rpm.
All other packages in the system are fully updated from the same source.
Kernel package is kernel-2.6.17-1.2187_FC5.i686.rpm.
I'm in the UK. The DVB device is identified by the kernel as
dvb-usb: WideView WT-220U PenType Receiver (Typhoon/Freecom),
purchased as a Freecom DVB-T
Here's what appears to be the relevant portion of the output from
mythbackend during a transcode. The crucial line seems (to me) to be
