When I pause something on my PVR using the Telus remote, and then hit pause again on the Telus remote, it resumes playing. Always has as far as I remember.
Are you using the Telus provided remote or one from Sony?
Have you been able to find a solution for this problem? I have a Sony A80J and the Sony remote just started to have the same issue, unable to pause OptikTV. I can pause using the original TELUS remote but the Sony remote can only un-pause, not pause.
