I've finally caught myself up to technology and got a DVR from Comcast ---

I've been having some problems and wondering if these are normal with DVR units or I should exchange it for another one--

When I fast-forward through portions, often, the video starts to play for 30 seconds or so and then audio catches up--therefore, the entire thing is out of sync, however, if I rewind and go back to a commercial--and allow it to catch up during that part--the video and audio are in sync. Is this normal? I didn't even realize the audio and video was captured on separate tracks on the DVR.
(I'd love an explanation on how DVR captures..)

Any help would be appreciated!

Thanks !

I have no idea what Comcast uses for a DVR box.

I can say that I did not have that problem with my DirecTivo and I do not have it with my new Direct TV HD-DVR

Cable DVRs in general have various weird issues like this.

Do you have a "Instant Replay"-type button? Something that only skips back about 3 seconds? I've seen this correct sync issues and it's quicker to use.

I have one through Time Warner that will start doing that on occasion. Usually unplugging the box and letting it reset will take care of it for a few months.

i love tivo.

i got nothing.
