video replay keeps freezing

I hope this is the right place to ask this question. I have a 2.4 Gh PC connected via ethernet cable to my PS3. I will usually re-encode MKV files to MPG using mkv2vob because I am hard of hearing and I want to hard encode subtitles. The media files are stored on my computer hard drive & I use PS3 media Player to play the files on TV through my PS3. For some reason, lately I have had problems with the playback being extremely jerky. It will continually stop for a second or so, continue on, freeze again, etc. I have moved the media files to a different hard drive, replaced the ethernet cable and tried other media players (i.e. mezzmo & TVersity) - no change. I'm even starting to notice it when I replay AVI files, although not nearly as bad. I have been playing re-encoded MKV to MPG files for some time with no problem until recently.

Any ideas?? confused

Thanks!!

 

Looking good, all the best mate
