Ok so I don't really understand the Recording Profiles setup but
here's what I have:
There are options, Hardware DVB Encoders & Transcoders
Under Hardware DVB Encoders there are 4 profiles, Default, LiveTV,
High Quality and Low Quality. None of them have "Enable auto-transcode
after recording" checked.
Under Transcoders there are 6 profiles: Autodetect from RTjpeg/MPEG4,
Autodetect from MPEG2, High Quality, Medium Quality, Low Quality

So if I understand this correctly there is no transcoding happening
right now in LiveTV or with recordings (which are using the default
profile) so they should all behave the same.

What other reason could there be for the terrible ffw/rew response on
my recordings?
