Cory, I have been looking at a great way to get my recordings to looks a lot better after transcode , but havent found anything acceptable. Instead I have had to just deal with the size of the recordings thrown at me from my PVR250 and deal. Do you just transcode as a job right from myth to 352x480, or do you have a process you follow after your recordings are all done?
