Converting WTV to TS

After using a number of DVR software packages I’m thinking of going back to WMC. Presently I edit my TS using Avidemux and then use Handbrake to convert to MP4. I’ve tried converting my WTV files to TS using the TS unprocessed profile using max width of 7680 and quality of 50%. The resulting TS file seems to have less quality than if I use regular software package(TVheadend, NextPVR etc) record the shows as TS. Is there some way to improve the quality of the TS file?

Unprocessed profiles copy the audio and video as is without any modifications. Are you using the Premium version of MCEBuddy? With the premium version it’ll disable the quality and max width sliders and has better support for stream copying.
