I have a lot of MPEG-TS files (.TS container but H.264 video) and playback is fine except that when you skip forward/backward or fast forward it's very sluggish and gets pixelated, etc.

I've been trying to do research and I'm guessing that they were encoding with very few reference blocks (ie. it's a capture from a DVB-S satellite stream).

When I re-encode them with Handbrake (.MP4 container) they play very, very good and seeking in the video is instant, etc, etc.

Is it possible to transcode/re-encode my MPEG-TS files with minimal quality loss? If so, what is my best bet? They are each about 2 Mbps (ie. 2 GB per hour) but I don't want to re-encode them if "minimal quality loss" requires 10+ GB per file. I'm hoping to keep the video are the same size.

Can anybody give me any advice?
